It any of these items is missing, call our Customer Support Hotline. ACCESSORIES Humminbird offers a wide assortment of accessories that complement and expand the capability of your new fishfinder. These accessories are designed with the same high standards and are backed by the same one-year warranty. The Humminbird Accessory catalog included with your unit contains descriptions of the many accessories available and ordering information. All Humminbird accessories are available through your full-service Humminbird dealer or factory direct through our number listed in the Customer Support section. INSTALLATION OVERVIEW Your Humminbird fishfinder consists of two primary components to install: the control head and the transducer. The control head contains the sonar transmit and receive circuitry, as well as the user controls and display. It should be installed in a location that provides access to the controls and visibility while in use. The control head mounts on a quick disconnect mounting system that swivels and tilts providing flexibility for viewing from almost anywhere on the boat. The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives the reflected sound waves and converts them back into electrical signals for display on the control head. It should be installed in contact with the surface of the water in an area that has smooth waterflow- usually on the transom of the boat. There are several mounting options for the transducer. Review the following section to determine the method that works for you and your boat.
INSTALLATION OVERVIEW Determining How to Mount the Transducer Your Humminbird fishfinder includes a standard transducer. This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat. The transom installation, which is the most widely used, places the transducer on the outside of the boat hull. This technique produces the least signal loss, and provides a way to adjust the transducer after installation. The mounting hardware included is designed to protect both the boat and the transducer should the boat strike debris in the water or when trailering. As an alternative to transom mounting, it is possible on many fiberglass-hulled boats to glue the transducer on the inside of the boat hull. Since fiberglass has similar sonar characteristics as water, the sonar signal can pass through the boat hull with minimal loss. The hull of the boat must be single layer construction (not double-hulled) Also, any air trapped in the lamination of the fiberglass would prevent the sonar signal from passing through. Inside the hull installations require no holes be drilled into the boat and through experimentation, high-speed operation comparable to transom mounting can be achieved. Two-part slow cure epoxy (not included) is required to glue the transducer in place.
ALTERNATE MOUNTING METHODS ALTERNATE TRANSDUCERS AND MOUNTING METHODS Your Humminbird fishfinder comes with everything necessary for installation and operation on most boats. However, there are several situations which may require a different type of transducer. Inboard boats, wood or metal hulls, and sail boats create unique transducer mounting needs Alternate transducers and mounting methods are detailed below. Portable Mounting The standard transducer can be adapted for portable installations with a portable mounting kit available from Humminbird. This accessory adapts your transducer to a suction cup mount for temporary installation on the boat hull or other surface. Trolling Motor Mounting The standard transducer can also be adapted to mount on most trolling motors using a different accessory kit. This accessory includes a bracket and hose clamp that allows mounting the transducer to the body of most trolling motors. Thru-Hull Mounting Thru-hull transducers install through a hole drilled in the hull of the boat. Larger boats or boats with inboard motors create turbulence that make transom mounting ineffective. Also, hulls that are very thick or are double layered, or made from materials such as wood or metal, (which do not conduct sonar signals) make inside the hull mounting inadvisable. Thru-hull mounting may require the use of a fairing block to level the transducer with the waterline. Also, since special tools and knowledge may be required to perform this type of installation, it is best to refer to a qualified marine technician.

TRANSDUCER EXCHANGE TRANSDUCER EXCHANGE Other transducers are available as replacements for the standard transducer. You may exchange your new and unassembled transducer for another type by returning it to the address listed in Customer Support. Some transducers may have additional cost. Refer to the Accessory catalog or call Customer Support for information. BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder. The installation guide included on the next few pages provides detailed step by step instructions for installation of the control head and transducer. For transom mount transducer installations you will need the mounting template included with your manual. In addition to the parts included you need the following for installation and operation: A powered hand drill and various drill bits Philips and flat-head screwdrivers A ruler or measuring tape Pen or pencil 12 volt power source (your boats battery) A 1-amp fuse A fuse holder (if you are wiring directly to the boats battery) Silicone sealant (for sealing drilled holes) 2-part, slow-cure epoxy (for inside the hull transducer installations)

INSTALLATION

TRANSOM INSTALLATION Do not begin this transducer installation until you read the Installation Preparation in the Operation Guide. This chapter contains information critical to the correct installation of your transducer. Due to the wide variety of boat hulls, only general instructions are presented in the installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. TRANSOM INSTALLATION Step One - Determine Where to Mount the Transducer Begin the transducer installation by determining where on the transom to install the transducer. Consider the following to find the best location: It is very important to locate the transducer in an area which is relatively free of turbulent water, As a boat moves through the water, turbulence is generated by the weight of the boat, and the thrust of the propeller(s). This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s) (Figure 1). On outboard or inboard/outboard boats it is best to stay at least 15 (40cm) to the side of the propeller(s). If possible, viewing the transom of the boat while the boat is moving will provide the best means of locating turbulence free water. If maximum high-speed operation is a high priority, this is the recommended method. If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat, and free of protrusions or ribs. The transducer when mounted should point straight down. The design of the transducer will accommodate a wide range of deadrises and remain ported straight down (Figure 2). On boats with stepped hulls, it may be possible to mount the transducer on the step. Never mount the transducer on the transom behind a step, as this area of the transom will not be in contact with the water at high speed (Figure 3).

TRANSOM INSTALLATION If the propeller(s) is (are) forward of the transom, it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered.
Step Two - Drill the Mounting Holes 1. Remove the mounting template from the front of the Operations Manual. 2. Hold the template on the transom of the boat in the location where the transducer will be installed (Figure 4). Align the template vertically, ensuring the lower edge of the transom meets with the bottom corner of the template. 3. Using a pencil or punch, mark the two mounting holes shown on the template onto the transom. Do not mark or drill any other holes at this time. 4. Using a 5/32 (4mm) bit drill the two holes to a depth of approximately 1" (3cm). On fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating. Step Three - Assemble the Transducer 1. Attach the Pivot to the transducer body as shown in Figure 5, using the #8 3/8 (9mm) long allen headed pivot screw, the headed pin, the two flat washers, and the two toothed lock washers. Note: The toothed lock washers must be positioned between the transducer and the pivot ears. The flat washers must be positioned to the outside at the pivot ears. 2. Using the AIlen wrenches provided, loosely tighten the pivot screw (Figure 6). Do not completely tighten the assembly at this time, so the pivot angle can be adjusted later. 3. Insert the pivot/transducer assembly into the mounting bracket as shown in Figure 7. Do not snap the assembly closed.
TRANSOM INSTALLATION Step Four - Mount the Transducer to the Transom 1. Apply silicone sealant to the mounting holes drilled into the transom. 2. Align the transducer assembly with the drilled holes in the transom (Figure 8). 3. Use either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm) socket to mount the assembly. Using the two #(25mm) long slotted hex head screws, mount the transducer assembly to the transom as shown. Do not fully tighten the mounting screws in order to vertically adjust the transducer. Snap the pivot down into place. Step Five - Adjust the Running Position of the Transducer The bracket allows height and tilt adjustment, the pivot screws allow angular adjustment. Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the instillation after high speed testing. 1. First adjust the pivot angle of the transducer body so its length is parallel with the length of hull of the boat. Then pivot the transducer down so the rear is about 1/4 inch (6mm) lower than the front (Figure 9). 2. Fully tighten the two pivot screws using the Allen wrenches. It may be necessary to retighten the pivot screws after the initial use as the plastics may still be seating to the lock washers. 3. Adjust the height of the assembly so the face of the transducer is 3/16" (4.5mm) beneath the lower edge of the transom (Figure 10). Mark the position of the mounting bracket on the transom with a pencil. 4. Force the pivot to the up position to gain access to the mounting screws. Assure the transducer location has not changed, then fully tighten the two mounting screws (Figure 11). Snap the pivot back down. Confirm the pivot angle has not changed. Note: A third screw location is provided for the

mounting bracket. Drill this hole and install the screw after final testing and adjustments have been completed.
TRANSOM INSTALLATION Step Six - Route the Cable There are several ways to route the transducer cable to the to the area where the control head will be installed. The most common procedure routes the cable through the transom into the boat. Inside the boat there is often a channel or conduit used for other wiring that the cable can be routed along. Do not cut or shorten the transducer cable and try not to damage the cable insulation. Route the cable as far as practical from the VHF radio antenna cables or tachometer cable to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50' (15 m). Call Humminbird Customer Support for more information. Follow these steps to route the cable through the transom: 1. Drill a 5/8 (16mm) hole above the water line. Route the cable through the hole. 2. Fill the hole with silicone sealant. 3. Place the escutcheon plate over the hole and attach with the two #8 x 5/8 (16mm) screws. 4. Secure the cable by attaching the cable camp to the transom using a #8 x 5/8 (16mm) screw. Note: The transducer will pivot up to 90 degrees in the bracket. Allow enough slack in the cable for this movement. It is best to route the cable to the side of the transducer so the cable will not be damaged by the transducer during movement.
INSIDE THE HULL INSTALLATION INSIDE THE HULL INSTALLATION Inside the hull installation requires the mount system and control head be installed and operational. See Installing the Control Head for instruction on installing the unit. Inside the hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird cannot guarantee depth performance when transmitting and receiving through the hull of the boat since some signal loss occurs. The amount of loss depends on hull construction and thickness, and the installation. This installation requires slow-cure two-part epoxy. Do not use silicone or any other soft adhesive to install the transducer, as this material reduces the sensitivity of the unit. Five minute epoxy has a tendency to cure before all the air bubbles can be purged. Step One - Determine the Mounting Location Begin the transducer installation by determining where inside the hull to install the transducer. Consider the following to find the best location: Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid ribs, strakes, and other protrusions as these create turbulence (Figure 14). As a general rule, the faster the boat can travel the further aft and closer to the centerline of the hull the transducer has to be located to remain in contact with the water at high speeds.
Step Two - Test the Mounting Location There is no opportunity for adjustment after the transducer glued in place. Therefore, it is best to perform a trial installation on inside the hull transducers first, and run the boat at high speeds to determine the best mounting area. 1. At the identified mounting location, lay the transducer body face down with the pointed end towards the bow. 2. Fill the hull with enough water to submerge the transducer body. Use a sand filled bag or other heavy object to hold the transducer in position.

The transducer cannot transmit through air. The water purges any air from between the transducer and the hull and fills any voids in the coarse fiberglass surface.
INSIDE THE HULL INSTALLATION 3. Power up the Control Head. 4. Run the boat at various speeds and water depths while observing the screen on the Control Head. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fishfinder in water at the desired depth. Test different locations in the hull until the optimum performance is achieved. Step Three - Permanently Mount the Transducer 1. Once the mounting location is determined, mark the position of the transducer. 2. Remove the water from inside the hull and thoroughly dry the mounting surface. If the surface is excessively rough, it may be necessary to sand the area to provide a smooth mounting surface. Ensure the mounting area is clear and dry. 3. Mix an ample quantity of two-part slow-cure epoxy slowly and thoroughly. Avoid trapping air bubbles. 4. Coat the face of the transducer and the inside of the hull (Figure 16). 5. Press the transducer into place with a slight twisting motion to purge any trapped air from underneath, keeping the pointed end of the transducer body pointed forward (Figure 17). Note: Proper operation requires the pointed end of the transducer body to face towards the bow. 6. Weight the transducer so it does not move while the epoxy is curing. When the epoxy cures, no water is necessary inside the hull. Neither water, spilled gasoline, or oil will affect the performance of the transducer.
CONTROL HEAD INSTALLATION CONTROL HEAD INSTALLATION Step One - Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine best location: The cables for power, transducer and temp/speed accessories (if applicable) should be installed first and must reach the mounting location. Extension cables are available. There are two ways to route the cables to the unit: through a hole in the mounting surface underneath the mounting bracket or from a hole outside the mounting bracket. Routing the cables down under the mount provides maximum weather protection; however this is not always feasible if the area under the fishfinder is inaccessible. In this case, route the cables through a hole at another location and cover with the supplied hole cover. The mounting surface should be adequately supported to protect the fishfinder from excessive wave shock and vibration, and provide visibility while in operation. The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy removal and installation (Figures 18-19).

Optional: If the cables pass outside the mounting bracket, install the hole cover over the hole and fasten in place using the two #8 x 7/8 (22mm) wood screws (Figure 24).
CONTROL HEAD INSTALLATION Step Five - Assembling the Connector Holder 1. Insert the cable connectors into the connector holder. The cable connectors are labeled, and there are corresponding labels on the connector holder (Figure 26). The slots for the connectors are keyed to prevent reverse installation, so do not force the connector into the holder. 2. Carefully pull the excess cable from beneath the mounting surface so the connector holder aligns with the mounting holes on the front of the mounting bracket (Figure 27). 3. Snap the support plate to the rear of the connector holder (Figure 28). 4. Insert the connector holder into place and use the two #6-32 x (9mm) screws to fasten it to the mounting bracket (Figure 28). 5. Install the control head by sliding it onto the mounting bracket until it is fully seated. To remove the unit simply depress the latch on the rear of the unit and lift (Figure 29). Your Humminbird is now ready for operation.
TEST THE INSTALLATION TEST THE INSTALLATION Testing should be performed with the boat in the water, however you can initially confirm basic operation with the boat trailered. Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed to confirm the button press. If the unit does not power-up, ensure the unit is fully seated on the mount and that power is available. The first screen provides four options: Start-up, Options, Simulator, and Diagnostic. A message at the bottom of the screen indicates the transducer connection. If no transducer is detected (or one is not connected), the message will indicate this and the unit will go into simulator after the initial screen times out. Note: the transducer must be submerged in water for reliable transducer detection. If a transducer is detected, the unit will enter Start Up or normal operation unless you choose another option. If you do not press any button before the timer reaches 0, the normal operation screen is displayed. If the boat is in water, sonar data appears. If the bottom is visible on screen with a digital depth readout, the unit is working properly. Ensure the boat is in water greater than 2 but less than the depth capability of the unit and the transducer is fully submerged. Remember the sonar signal cannot pass through air. If the unit is working properly gradually increase the boat speed to test highspeed performance. If the unit-functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment. Refer to the appropriate transducer installation section for more detail. Note: it is often necessary to make several incremental transducer adjustments before optimum high-speed performance is achieved. Important: For Transom Mount transducer installations, install the third mounting screw after the final transducer adjustments.

USING THE WIDE W

The Wide W is easy to use. Simply press the POWER button, and the unit will automatically locate the bottom. Adjust the depth range and sensitivity to an appropriate level, and draw a picture of the terrain beneath your boat. If POWER is the only button you press, you will benefit from the advanced automatic bottom tracking capability of the unit. However, if you choose to experiment with the many features and controls the Wide W offers, you can customize the presentation of information to suit your particular needs. The Wide W offers a wide variety of settings and types of display, to satisfy any sonar need.

SIMULATOR OPERATION

The Wide W contains a simulator which allows you to use the unit as if you were on the water. This simulator is invaluable for learning how to operate the many features of the Wide W unit. With the unit turned off, press and hold POWER until you hear a continuous chirp This initiates the simulator operation. Your Wide W will simulate all functions as if you were actually on the water. To exit the simulator, press POWER to turn the unit off. Pressing POWER again will power-up the unit for normal operation. When in simulator operation, the Wide W unit will respond to control inputs as if it were in actual operation, so feel free to experiment with the many features and functions to customize the Wide W unit to your particular application.

WHAT YOU SEE ON SCREEN

The first thing you may notice about the Wide W unit is the high-resolution screen LCD display. The LCD display uses super-twist technology, for maximum viewability and is ruggedized for tough shock and vibration endurance. The display can operate at temperatures more extreme than you are likely to encounter.
There are three basic screen layouts for the Wide W. Figure A shows the default screen layout which does not include temperature and speed readings. If you have purchased the temperature and speed accessory and it is installed, the screen layout will be slightly different as shown in Figure B.
Later, you will learn of another feature called advanced operation. This feature uses yet another screen layout as shown in Figure C which maximizes the display for the terrain and target presentation.
The number of vertical pixels (picture elements or dots) in a given depth range determines the display resolution, or ability to differentiate targets close to the bottom or other targets. The Wide W is capable of distinguishing between targets only 6 inches apart, and show fish within 6 inches of the bottom. On all screens the horizontal line at the top of the display is the Zero line. The Zero line will always have a gap which moves as the screen updates. This gap lets you know that the display is updating even if the bottom terrain remains the same or is not visible on the selected depth range. The farthest right column of information is the most recent information, and it shows what is directly under your boat. At power-up, the Wide W locates the bottom and adjusts the depth range to a setting most appropriate for that depth. The bottom will be usually shown about 2/3 of the way down the display. The Structure ID depiction of the bottom will vary in appearance depending on the bottom terrain. If the bottom is very hard and smooth, the bottom depiction will be narrow and dense. If

the bottom is mud or soft sand, the bottom depiction will be thick and less dense. This indicates that much of the sonar signal is absorbed by the soft bottom. If the bottom is rugged and varying, such as a rocky bottom, the depiction will be textured and vary in density. Structure, such as submerged trees or brush, or other objects are clearly displayed above the soid bottom return, in varying degrees of pixelization. This bottom depiction is useful in locating structure, by comparing relative density as well as depth.
The transmitted sonar signal travels downward, and is reflected back toward the surface by the bottom of other objects for display on-screen. The signal does not stop there it is reflected downward again by the surface of the water, and a weak second return is usually visible if the depth range is sufficient to see it. A second return is shown in the figure below. Some users use this second return as an indicator when setting the sensitivity bias. If a target is detected between the surface and the bottom, it is displayed as a fish symbol. Depending on the strength of the signal reflected from the object, one of three different size symbols is used. These reflected signals are normalized foe depth, so that a small fish does not appear to be a large fish it it is close to the boat.
Since some species of fish tend to be better reflectors of sonar than others, the strength of return is not always an accurate indicator of fish size, however, typically the larger the fish, the larger the signal return.

CONTROL FUNCTIONS

The Wide W unit uses only seven buttons to control all functions. The controls are divided into two groups: POWER, STOP, and LIGHT are one group, and the Menu System controls are the other group. When any button is pressed, an audible chirp will verify the control input.
POWER, as previously discussed, powers the Wide W for normal operation. Also, if the unit is powered off, press and hold POWER until you hear a continuous chirp to enable simulator operation, as discussed in Simulator Operation. Pressing POWER when the unit is in normal or simulator operation will power the unit off. STOP freezes the display to allow closer study. Pressing STOP again will resume normal operation. Also if a menu is on-screen until STOP is pressed again. LIGHT enables a two-level display back light. Pressing once will turn the light on low, pressing a second time will increase the back light to the high setting, and pressing a third time will turn the back light off. The four remaining buttons work together to control the Menu System- an array of menu controlled functions. Menu brings a menu on-screen for adjustment, or if a menu is already present, the next menu in sequence will appear. Menus will go off-screen and normal operation will resume after a short period of time. If you wish to keep the menu on-screen for an extended period of time, press STOP. UP arrow selects the next larger or next sequential adjustment within the menu. Holding an Arrow button down will cause the unit to continue to make the adjustment, until a limit is reached, and the limit alarm sounds. DOWN arrow selects the next smaller adjustment within the menu. ENTER is used to toggle other menu options on and off.

All menus use the same general layout as shown in the sample men at the right. The heading of the menu is at the top. The area in the center is controlled by the UP and DOWN arrows, and the area under the horizontal line is controlled by the ENTER button. Not all menus are affected by all controls, but the layout is the same regardless. Pressing MENU repeatedly will sequentially display all available menus.

MENU FUNCTIONS

The following section explains each menu in detail, and how these adjustments can be used to obtain the maximum information from the sonar returns. SENSITIVITY As the Wide W receives returned signals, the sensitivity of the receiver as adjusted automatically based on a number of factors such as the depth of the water, and the signal clarity. In murky water, full of debris, The Wide W will select a lower sensitivity setting. In Clear water, where there is little debris to defract the sonar signal, the sensitivity is set higher.
The Sensitivity menu allows you to bias this automatic setting up or down based on personal preference.
You can select a bias of +5 to 5, for 11 different bias settings. A bias setting of 0 has no effect on the automatic function. A +3 setting selects a sensitivity setting three steps higher than the unit would normally select, so even the smallest returns are displayed on the screen. A setting of 2 sets the sensitivity two steps below what the unit would normally select, so only the largest targets or other returns are displayed.
Another use of the Sensitivity menu is to select the bottom representation. The Wide W normally displays a variable Structure ID bottom, which can allow experienced users to determine the texture or relative hardness of the bottom. For simplicity, you can select a black bottom using the ENTER button. This blackens in the display below the bottom for easiest recognition of the bottom location, even from a great distance.
RANGE The Wide W adjusts the depth range automatically, so the bottom return is displayed at the bottom 1/3 of the display. This leaves the top 2/3 to display anything between the surface and the bot tom. As your boat moves over deeper or shallower water, the unit adjusts the depth range of the display to keep the bottom return in the same general area on the screen.
However, you may choose to control this range adjustment manually. By pressing ENTER, you can select manual operation, meaning the unit will no longer adjust the depth range automatically. The depth range selected is controlled by the UP and DOWN arrow buttons. Ranges of 0-15 feet, 30 feet, 60 feet, 120 feet, 180 feet, 240 feet, 360 feet 480 feet, & 600 feet can be selected. An onscreen icon indicates whether the unit is in Auto or MNL (manual) range control. If you alter the depth range, Manual operation is automatically selected. This feature is valuable if you are only interested in targets near the surface. The Wide W will always display the digital depth of the water, regardless of whether the bottom is shown on the selected depth range.

ZOOM Another form of range control is Zoom. Zoom allows selection of various ranges for full screen viewing, not necessarily including the surface. By using the display to view a smaller area, the
effective display resolution is increased, and the units ability to separate targets close together is enabled. The zoom range is determined by the depth range in use when Zoom is enabled. IN shallow water, when the 15 foot or 39 foot depth is used, the zoom range will be 7-1/2 feet. If the 60 foot or 120 foot depth range is in use, the zoom range will be 15 feet, if a 180 foot - 480 depth ange is used, the zoom range will be 60 feet.
To enable Zoom, adjust the depth of the zoom range first using the UP and DOWN arrow buttons until the upper and lower limit numbers correspond with the range you wish to view, then enable Zoom using the ENTER button. Once you are in zoom, you may still adjust the depth of t he zoom range by using the UP and DOWN arrow buttons. The Zoom menu will not appear when an adjustment is made unless MENU is pressed. The digital depth readout will continue to track the bottom even when Zoom is enabled.
Bottom Lock is a function of zoom, except the depth adjustment is controlled automatically to view the area immediately above the bottom. This is especially useful if you are looking for structure or minor variations in terrain in areas of relatively flat bottom terrain. To enable Bottom Lock, Press ENTER until the BL is highlighted. The zoom range will be controlled by t he current depth range, as in Zoom, and will be indicated on the Zoom menu.

BOTTOM ALARM

The Wide W contains an audible alarm to warn you of shallow water depths. This alarm is adjustable from 2 feet to 99 feet of depth. To enable the alarm, simply adjust the alarm depth using the UP and DOWN arrow buttons, and press ENTER. Whenever the depth of the water
beneath your boat is equal to or less than the selected alarm depth, a continuous alarm will sound.
To disable the alarm, either move to deeper water, or select the Bottom Alarm menu, and press ENTER to turn the alarm off.

FISH ALARM

The Fish Alarm alerts you to the presence of fish, or other targets not attached to the bottom, in the water beneath your boat. The Fish Alarm has 3 different settings which correspond to the 3 different size fish targets shown on-screen.
To enable Fish Alarm, use the UP and DOWN arrow buttons to adjust the size return you want to be alerted to: large fish only, large and medium size fish, or all fish. Then press ENTER to enable the alarm. Remember that it is impossible for sonar to determine if a signal return is a fish or some other type of object or suspended debris. Any object not connected to the bottom is normally a fish and is portrayed as a fish symbol. The strength of the reflected sonar signal from a target is a good indicator of the size of the target, and the fish symbol displayed represents the strength of the signal reflected from it.

ID is the automatic identification of target returns based on the strength of the returned signal and other factors. Three options are available: ID On displays targets as one of three different size fish symbols.
ID+, the default setting, provides more information about the location of the target by attaching depth strings showing the digital depth of the target. When there are numerous targets onscreen, not every target depth is shown, to avoid excessive clutter on-screen. ID Off disables the units interpretation of targets and displays the raw sonar information as it is received. Advanced users may prefer this type of presentation, so they can make their own interpretation from the information displayed.

TRIPLOG

Triplog provides a time/distance calculation, based on input from the optional speed accessory. The timer is started when the unit is first powered, and distance information is collected to provide elapsed distance since power-up, and the average speed. To enable the Triplog display, press ENTER.
The Triplog can be reset at any time by pressing STOP. Press ENTER to return to the normal screen.
Note: The optional Temp/ Speed accessory must be connected for Triplog to work.
SYSTEM OPTIONS The System Options menu allows the adjustment of several features. These adjustments are usually made initially, and rarely thereafter. To make these adjustments, first enter the System Options full screen menu with the ENTER key. Then press MENU to choose the category for adjustment, the UP and DOWN arrow buttons to adjust the setting, and the ENTER key to return to the normal screen when you have finished.
Scroll Rate controls the rate of update of the display. There are five rate settings available. The default setting is rate 4- you may speed up or slow down the update rate to match your personal preference. To present the most accurate representation of the terrain beneath your boat, the scroll rate of the display should be approximately synchronized to the speed of the boat. If your boat is stationary or moving slowly, select a slower scroll rate, and if you typically operate the boat at high speeds, use a faster scroll rate.

User Level is used to select Normal or Advanced operation. Advanced Mode performs several functions which will benefit the experienced user. Icons are not shown and numerical data is smaller to allow more of the display to be used for the picture of the bottom. Several other changes in operation occur which are designed to increase the speed of adjustments, and maximize the graphic use of the display. Units is used to select the way in which the Wide W displays your boat speed. Two options are available, KTS and MPH. KTS displays your boat speed in knots or nautical miles per hour. MPH displays statute miles per hour. The units of measurement are always displayed on-screen. Boat speed and water temperature features require the use of the optional temp /speed accessory, which must be purchased separately.

All Humminbird accessories are available through your fullservice Humminbird dealer or factory direct through our number listed in the Customer Support section. INSTALLATION OVERVIEW Your Humminbird fishfinder consists of two primary components to install: the control head and the transducer. The control head contains the sonar transmit and receive circuitry, as well as the user controls and display. It should be installed in a location that provides access to the controls and visibility while in use. The control head mounts on a quick disconnect mounting system that swivels and tilts providing flexibility for viewing from almost anywhere on the boat. The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives the reflected sound waves and converts them back into electrical signals for display on the control head. It should be installed in contact with the surface of the water in an area that has smooth waterflow- usually on the transom of the boat. There are several mounting options for the transducer. Review the following section to determine the method that works for you and your boat.
INSTALLATION OVERVIEW Determining How to Mount the Transducer Your Humminbird fishfinder includes a standard transducer. This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat. The transom installation, which is the most widely used, places the transducer on the outside of the boat hull. This technique produces the least signal loss, and provides a way to adjust the transducer after installation. The mounting hardware included is designed to protect both the boat and the transducer should the boat strike debris in the water or when trailering. As an alternative to transom mounting, it is possible on many fiberglass-hulled boats to glue the transducer on the inside of the boat hull. Since fiberglass has similar sonar characteristics as water, the sonar signal can pass through the boat hull with minimal loss. The hull of the boat must be single layer construction (not double-hulled) Also, any air trapped in the lamination of the fiberglass would prevent the sonar signal from passing through. Inside the hull installations require no holes be drilled into the boat and through experimentation, high-speed operation comparable to transom mounting can be achieved. Two-part slow cure epoxy (not included) is required to glue the transducer in place.
ALTERNATE MOUNTING METHODS ALTERNATE TRANSDUCERS AND MOUNTING METHODS Your Humminbird fishfinder comes with everything necessary for installation and operation on most boats. However, there are several situations which may require a different type of transducer. Inboard boats, wood or metal hulls, and sail boats create unique transducer mounting needs Alternate transducers and mounting methods are detailed below. Portable Mounting The standard transducer can be adapted for portable installations with a portable mounting kit available from Humminbird. This accessory adapts your transducer to a suction cup mount for temporary installation on the boat hull or other surface. Trolling Motor Mounting The standard transducer can also be adapted to mount on most trolling motors using a different accessory kit. This accessory includes a bracket and hose clamp that allows mounting the transducer to the body of most trolling motors. Thru-Hull Mounting Thru-hull transducers install through a hole drilled in the hull of the boat. Larger boats or boats with inboard motors create turbulence that make transom mounting ineffective. Also, hulls that are very thick or are double layered, or made from materials such as wood or metal, (which do not conduct sonar signals) make inside the hull mounting inadvisable. Thru-hull mounting may require the use of a fairing block to level the transducer with the waterline. Also, since special tools and knowledge may be required to perform this type of installation, it is best to refer to a qualified marine technician.

TRANSDUCER EXCHANGE TRANSDUCER EXCHANGE Other transducers are available as replacements for the standard transducer. You may exchange your new and unassembled transducer for another type by returning it to the address listed in Customer Support. Some transducers may have additional cost. Refer to the Accessory catalog or call Customer Support for information. BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder. The installation guide included on the next few pages provides detailed step by step instructions for installation of the control head and transducer. For transom mount transducer installations you will need the mounting template included with your manual. In addition to the parts included you need the following for installation and operation: A powered hand drill and various drill bits Philips and flat-head screwdrivers A ruler or measuring tape Pen or pencil 12 volt power source (your boats battery) A 1-amp fuse A fuse holder (if you are wiring directly to the boats battery) Silicone sealant (for sealing drilled holes) 2-part, slow-cure epoxy (for inside the hull transducer installations)

INSTALLATION

TRANSOM INSTALLATION Do not begin this transducer installation until you read the Installation Preparation in the Operation Guide. This chapter contains information critical to the correct installation of your transducer. Due to the wide variety of boat hulls, only general instructions are presented in the installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. TRANSOM INSTALLATION Step One - Determine Where to Mount the Transducer Begin the transducer installation by determining where on the transom to install the transducer. Consider the following to find the best location: It is very important to locate the transducer in an area which is relatively free of turbulent water, As a boat moves through the water, turbulence is generated by the weight of the boat, and the thrust of the propeller(s). This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s) (Figure 1). On outboard or inboard/outboard boats it is best to stay at least 15 (40cm) to the side of the propeller(s). If possible, viewing the transom of the boat while the boat is moving will provide the best means of locating turbulence free water. If maximum high-speed operation is a high priority, this is the recommended method. If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat, and free of protrusions or ribs. The transducer when mounted should point straight down. The design of the transducer will accommodate a wide range of deadrises and remain ported straight down (Figure 2). On boats with stepped hulls, it may be possible to mount the transducer on the step. Never mount the transducer on the transom behind a step, as this area of the transom will not be in contact with the water at high speed (Figure 3).

TRANSOM INSTALLATION If the propeller(s) is (are) forward of the transom, it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered.
Step Two - Drill the Mounting Holes 1. Remove the mounting template from the front of the Operations Manual. 2. Hold the template on the transom of the boat in the location where the transducer will be installed (Figure 4). Align the template vertically, ensuring the lower edge of the transom meets with the bottom corner of the template. 3. Using a pencil or punch, mark the two mounting holes shown on the template onto the transom. Do not mark or drill any other holes at this time. 4. Using a 5/32 (4mm) bit drill the two holes to a depth of approximately 1" (3cm). On fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating. Step Three - Assemble the Transducer 1. Attach the Pivot to the transducer body as shown in Figure 5, using the #8 3/8 (9mm) long allen headed pivot screw, the headed pin, the two flat washers, and the two toothed lock washers. Note: The toothed lock washers must be positioned between the transducer and the pivot ears. The flat washers must be positioned to the outside at the pivot ears. 2. Using the AIlen wrenches provided, loosely tighten the pivot screw (Figure 6). Do not completely tighten the assembly at this time, so the pivot angle can be adjusted later. 3. Insert the pivot/transducer assembly into the mounting bracket as shown in Figure 7. Do not snap the assembly closed.
TRANSOM INSTALLATION Step Four - Mount the Transducer to the Transom 1. Apply silicone sealant to the mounting holes drilled into the transom. 2. Align the transducer assembly with the drilled holes in the transom (Figure 8). 3. Use either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm) socket to mount the assembly. Using the two #(25mm) long slotted hex head screws, mount the transducer assembly to the transom as shown. Do not fully tighten the mounting screws in order to vertically adjust the transducer. Snap the pivot down into place. Step Five - Adjust the Running Position of the Transducer The bracket allows height and tilt adjustment, the pivot screws allow angular adjustment. Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the instillation after high speed testing. 1. First adjust the pivot angle of the transducer body so its length is parallel with the length of hull of the boat. Then pivot the transducer down so the rear is about 1/4 inch (6mm) lower than the front (Figure 9). 2. Fully tighten the two pivot screws using the Allen wrenches. It may be necessary to retighten the pivot screws after the initial use as the plastics may still be seating to the lock washers. 3. Adjust the height of the assembly so the face of the transducer is 3/16" (4.5mm) beneath the lower edge of the transom (Figure 10). Mark the position of the mounting bracket on the transom with a pencil. 4. Force the pivot to the up position to gain access to the mounting screws. Assure the transducer location has not changed, then fully tighten the two mounting screws (Figure 11). Snap the pivot back down. Confirm the pivot angle has not changed. Note: A third screw location is provided for the mounting bracket. Drill this hole and install the screw after final testing and adjustments have been completed.

TRANSOM INSTALLATION Step Six - Route the Cable There are several ways to route the transducer cable to the to the area where the control head will be installed. The most common procedure routes the cable through the transom into the boat. Inside the boat there is often a channel or conduit used for other wiring that the cable can be routed along. Do not cut or shorten the transducer cable and try not to damage the cable insulation. Route the cable as far as practical from the VHF radio antenna cables or tachometer cable to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50' (15 m). Call Humminbird Customer Support for more information. Follow these steps to route the cable through the transom: 1. Drill a 5/8 (16mm) hole above the water line. Route the cable through the hole. 2. Fill the hole with silicone sealant. 3. Place the escutcheon plate over the hole and attach with the two #8 x 5/8 (16mm) screws. 4. Secure the cable by attaching the cable camp to the transom using a #8 x 5/8 (16mm) screw. Note: The transducer will pivot up to 90 degrees in the bracket. Allow enough slack in the cable for this movement. It is best to route the cable to the side of the transducer so the cable will not be damaged by the transducer during movement.
INSIDE THE HULL INSTALLATION INSIDE THE HULL INSTALLATION Inside the hull installation requires the mount system and control head be installed and operational. See Installing the Control Head for instruction on installing the unit. Inside the hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird cannot guarantee depth performance when transmitting and receiving through the hull of the boat since some signal loss occurs. The amount of loss depends on hull construction and thickness, and the installation. This installation requires slow-cure two-part epoxy. Do not use silicone or any other soft adhesive to install the transducer, as this material reduces the sensitivity of the unit. Five minute epoxy has a tendency to cure before all the air bubbles can be purged. Step One - Determine the Mounting Location Begin the transducer installation by determining where inside the hull to install the transducer. Consider the following to find the best location: Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid ribs, strakes, and other protrusions as these create turbulence (Figure 14). As a general rule, the faster the boat can travel the further aft and closer to the centerline of the hull the transducer has to be located to remain in contact with the water at high speeds.

Step Two - Test the Mounting Location There is no opportunity for adjustment after the transducer glued in place. Therefore, it is best to perform a trial installation on inside the hull transducers first, and run the boat at high speeds to determine the best mounting area. 1. At the identified mounting location, lay the transducer body face down with the pointed end towards the bow. 2. Fill the hull with enough water to submerge the transducer body. Use a sand filled bag or other heavy object to hold the transducer in position. The transducer cannot transmit through air. The water purges any air from between the transducer and the hull and fills any voids in the coarse fiberglass surface.
INSIDE THE HULL INSTALLATION 3. Power up the Control Head. 4. Run the boat at various speeds and water depths while observing the screen on the Control Head. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fishfinder in water at the desired depth. Test different locations in the hull until the optimum performance is achieved. Step Three - Permanently Mount the Transducer 1. Once the mounting location is determined, mark the position of the transducer. 2. Remove the water from inside the hull and thoroughly dry the mounting surface. If the surface is excessively rough, it may be necessary to sand the area to provide a smooth mounting surface. Ensure the mounting area is clear and dry. 3. Mix an ample quantity of two-part slow-cure epoxy slowly and thoroughly. Avoid trapping air bubbles. 4. Coat the face of the transducer and the inside of the hull (Figure 16). 5. Press the transducer into place with a slight twisting motion to purge any trapped air from underneath, keeping the pointed end of the transducer body pointed forward (Figure 17). Note: Proper operation requires the pointed end of the transducer body to face towards the bow. 6. Weight the transducer so it does not move while the epoxy is curing. When the epoxy cures, no water is necessary inside the hull. Neither water, spilled gasoline, or oil will affect the performance of the transducer.
CONTROL HEAD INSTALLATION CONTROL HEAD INSTALLATION Step One - Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine best location: The cables for power, transducer and temp/speed accessories (if applicable) should be installed first and must reach the mounting location. Extension cables are available. There are two ways to route the cables to the unit: through a hole in the mounting surface underneath the mounting bracket or from a hole outside the mounting bracket. Routing the cables down under the mount provides maximum weather protection; however this is not always feasible if the area under the fishfinder is inaccessible. In this case, route the cables through a hole at another location and cover with the supplied hole cover. The mounting surface should be adequately supported to protect the fishfinder from excessive wave shock and vibration, and provide visibility while in operation. The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy removal and installation (Figures 18-19).

CONTROL HEAD INSTALLATION Step Five - Assembling the Connector Holder 1. Insert the cable connectors into the connector holder. The cable connectors are labeled, and there are corresponding labels on the connector holder (Figure 26). The slots for the connectors are keyed to prevent reverse installation, so do not force the connector into the holder. 2. Carefully pull the excess cable from beneath the mounting surface so the connector holder aligns with the mounting holes on the front of the mounting bracket (Figure 27). 3. Snap the support plate to the rear of the connector holder (Figure 28). 4. Insert the connector holder into place and use the two #6-32 x (9mm) screws to fasten it to the mounting bracket (Figure 28). 5. Install the control head by sliding it onto the mounting bracket until it is fully seated. To remove the unit simply depress the latch on the rear of the unit and lift (Figure 29). Your Humminbird is now ready for operation.
TEST THE INSTALLATION TEST THE INSTALLATION Testing should be performed with the boat in the water, however you can initially confirm basic operation with the boat trailered. Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed to confirm the button press. If the unit does not power-up, ensure the unit is fully seated on the mount and that power is available. The first screen provides four options: Start-up, Options, Simulator, and Diagnostic. A message at the bottom of the screen indicates the transducer connection. If no transducer is detected (or one is not connected), the message will indicate this and the unit will go into simulator after the initial screen times out. Note: the transducer must be submerged in water for reliable transducer detection. If a transducer is detected, the unit will enter Start Up or normal operation unless you choose another option. If you do not press any button before the timer reaches 0, the normal operation screen is displayed. If the boat is in water, sonar data appears. If the bottom is visible on screen with a digital depth readout, the unit is working properly. Ensure the boat is in water greater than 2 but less than the depth capability of the unit and the transducer is fully submerged. Remember the sonar signal cannot pass through air. If the unit is working properly gradually increase the boat speed to test high-speed performance. If the unit-functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment. Refer to the appropriate transducer installation section for more detail. Note: it is often necessary to make several incremental transducer adjustments before optimum high-speed performance is achieved. Important: For Transom Mount transducer installations, install the third mounting screw after the final transducer adjustments.

TESTING THE INSTALLATION After installation is complete and all connections are made, you are ready to test the installation prior to actual use. Thorough testing should be performed with the boat in water, however, you can initially confirm basic operation with the boat trailered. Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed that confirms the button press. If the unit does not power-up, ensure that the unit is fully seated on the mount and that power is available. The first screen provides three options; Start-up, Simulator, and Diagnostic. The time remaining before the screen "times-out" is shown at the bottom of the screen. If you do not press any button before the timer reaches 0, the normal operation screen will be displayed. If the boat is on-water, sonar data will begin to appear. If the bottom is visible on-screen with a digital depth readout, the unit is working properly. If the unit powers-up but fails to display bottom information, the transducer is not properly connected. Ensure that the boat is in water greater than 2' but less than 600' deep, and that the transducer is fully submerged. Remember that the sonar signal cannot pass through air. Refer to the troubleshooting section of this manual. If the unit is working properly, gradually increase the boat speed to test high-speed performance. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer installation requires adjustment. Refer to the appropriate transducer installation section for more detail. NOTE: It is often necessary to make several incremental transducer adjustments before optimum highspeed performance is achieved.
The Wide 128 is completely automatic and easy to use. Simply press the POWER button and the unit will locate and track the bottom from 2' to 600' changing ranges as necessary, display any structure or suspended fish and work at speeds from 0 to over 70 mph. If POWER is the only button you use, you will benefit from the advanced automatic bottom tracking of the Wide 128. However, if you choose to experiment with the many features and controls the Wide 128 offers, you can customize the presentation of information to suit your particular needs.
SIMULATOR OPERATION The Wide 128 contains a simulator which allows you to use the unit as if you are on the water. The Simulator is invaluable for learning how to operate the many features of the Wide 128. There are two ways to enable the simulator: if the unit is powered off, press and hold the POWER button for approximately 3 seconds until a continuous chirp is heard. The Simulator can also be enabled by selecting the Simulator option on the start-up screen after you normally power-up the unit. When this screen is shown, simply press the DOWN ARROW until "Simulator" is highlighted. When the screen times-out, the unit will be in simulator mode. When in simulator operation, the Wide 128 responds to control inputs as if it is in actual operation, so feel free to experiment with the many features and functions to customize the Wide 128 for your particular operation. To exit Simulator mode, power the unit off.

WHAT YOU SEE ON-SCREEN Your Wide 128 uses a 64 x 128 matrix SuperTwist LCD display. This type of display provides outstanding viewability in all light conditions over a wide range of temperatures. NOTE: When in simulator mode, the word "simulator" occasionally scrolls across the display indicating that the information onscreen is not real sonar data. At power-up, the depth range , sensitivity, and other user adjustments are set at their default settings. There are several elements on-screen which are common to all modes of operation. The large digital number at the lower left of the display is the depth of the water directly beneath the transducer location. The range of the graphic display is shown to the right of the graphic information. The upper number is 0 indicating the surface of the water, the lower number is one of the 9 ranges available which best matches the depth of the water. As the depth of the water changes, the range changes as necessary in order to retain a bottom representation on-screen. When in Auto mode, the horizontal line at the top of the graphics area is the 0 line which represents the surface of the water. Occasionally there will be a gap in this line. This gap indicates that the unit is updating the display even if the bottom is not visible on-screen, or if the bottom information is not changing. The graphic representation of the bottom may vary considerably depending on the composition and regularity of the bottom surface (see Interpreting the On-screen Information). Any sonar return which is determined to be not a part of the bottom is shown between the surface and the bottom. If this return is determined to be a fish, one of several fish shapes is drawn which indicate size, depth, and location of the fish (see Interpreting the On-screen Information).
INTERPRETING THE ON-SCREEN INFORMATION Figure B shows a typical view you can expect to see on-water. New sonar information appears on the right side of the graphic area of the display and moves to the left as new information is displayed. The Wide 128 automatically selects the appropriate depth range to show the depth of water beneath the transducer. This range is selected so that the bottom representation is typically shown about 2/3 down the display. The graphic depiction of the bottom provides the user with an effective tool for understanding the composition of the bottom. If the bottom is hard and smooth, the bottom depiction is narrow and dense. If the bottom is soft mud

or sand, the depiction will be thick and less dense. This indicates that much of the signal is absorbed by the soft bottom. If the bottom is rocky or rugged in composition, the depiction is of varying density and textured in appearance. Wave action also affects the bottom depiction. Remember that the information drawn is a distance measurement, so if the boat is moving up and down over flat bottom, the bottom depiction often appears in regular variations which match wave timing. Structure is defined as any object physically attached to the bottom. The sonar configuration of the Wide 128 is optimized to give the most accurate depiction of bottom structure possible. Grass, trees, stumps, wrecks or other debris are accurately displayed, however the depiction of these objects varies with boat speed and direction. The best way to learn to interpret structure is to operate the Wide 128 over a variety of known conditions and experiment with user functions to best represent those conditions on-screen.
Sonar targets which are not physically attached to the bottom may take one of many shapes. Surface clutter is the layer of water near the surface which is rich in algae and other growth, and often is aerated by wind or wave action. This area of water interferes with sonar transmission and often appears onscreen as regular clusters of individual dots near the "0" line. Thermoclines are sharp differences in water temperature. These are easily identified by the continuous nature of the return.
ID+ adds an additional piece of information to help the user locate fish. On selected fish symbols, the digital depth of the designated fish is drawn to help locate the fish vertically. This is especially helpful in setting bait depths or for downrigger operation.
CONTROL FUNCTIONS The Wide 128 uses a simple 5-button keypad for all user input. When any button is pressed, an audible "chirp" confirms the control input. In the event that a particular button has no function or is inappropriate for the situation, an audible "error", or multiple chirps, will be heard. POWER, powers the Wide 128 up for normal operation. When the unit is on, POWER turns the unit off. POWER can also be used to go directly into Simulator mode. With the unit powered off, press and hold POWER for several seconds until a continuous chirp is heard. When a sonar signal is reflected off the bottom back to the transducer, there is often enough energy left in the signal to be reflected off the surface of the water back to the bottom a second time. Second returns appear as a slightly weaker bottom representation exactly twice the depth of the primary bottom return. The second return is most likely to occur in shallow water and in areas of relatively hard bottom. The Wide 128 uses advanced signal processing to further evaluate any sonar return between the surface and the bottom. For instance, a small school of bait fish usually appears as a dense cluster of individual dots. If the return meets certain additional criteria, a fish symbol will be assigned. There are three different size fish symbols used to indicate the intensity of the sonar return. While signal intensity is a good indicator of relative fish size, different species of fish have different sonar characteristics, so it is not always possible to distinguish fish size between varying species. The signal intensity is "normalized" for depth so that a small fish close to the boat does not appear as a large fish symbol. LIGHT controls the unit's 3-position display backlight. With the unit powered on, pressing LIGHT once will turn the backlight on "high". Pressing LIGHT a second time will turn the backlight on "low", and pressing a third time will turn the backlight off. The backlight is very effective for low-light and nighttime operation. When the backlight is on, the Wide 128 will consume more power than with the backlight off. This is important when using the Wide 128 in a portable configuration powered by a separate battery, or when powering the unit from a trolling motor battery. NOTE: When powering the unit from a battery such as in portable applications, avoiding use of the backlight prolongs battery life. The three lower buttons, MENU, UP ARROW, and DOWN ARROW work together to control the Wide 128 menu-controlled user functions. MENU brings a menu on-screen for adjustment. In normal operation, pressing MENU repeatedly will cycle through all available menu headings. When the desired menu heading is displayed, the full menu appears after a short pause. A menu remains on-screen for several seconds allowing user adjustment by means of the ARROW keys. If no adjustment is made in the allotted time, the menu disappears. If you need the menu to remain on-screen longer to study the adjustment options, press and hold MENU-the menu will remain on-screen indefinitely. Once you release the menu button, the screen will time out.

Once a menu times out, it is still considered the active menu. Pressing MENU will bring up the last used menu. The UP ARROW and DOWN ARROW make adjustments to menu functions. On the left side of every menu there are UP ARROW and DOWN ARROW symbols. The symbols indicate which ARROW button has a function in a particular situation. Either one or both ARROW buttons can be used to adjust the menu function. A hollow ARROW symbol means that the corresponding ARROW button has no function. Pressing that button will result in no adjustment and the "error" audible will be heard. A solid ARROW symbol means that the corresponding ARROW button can be used to affect the menu adjustment. The ARROW buttons often can be used when no menu is on-screen. In these situations, pressing the ARROW button affects the function of the active (last-used) menu. This is a short-cut to menu operation. The menu appears onscreen while the adjustment is made and 'times out'. A frequently used menu can be adjusted very quickly using this technique. After an adjustment is made to a menu function, the menu "times out" after several seconds and the unit returns to normal operation. All menus use the same basic layout as shown in Figure F. The heading at the top describes the menu function (see Control Functions for more details on individual functions). The UP ARROW and DOWN ARROW symbols to the left of the menu indicate which buttons are available for adjustment. In menus which have numerous possible settings such as depth range, a range of adjustment indicator shows the total range available and the current setting. Within the menu are the options available. The selected option or current setting is highlighted in the black box. If no adjustment is made, this will be the selected setting. Pressing one of the ARROW buttons while the menu is on-screen selects another option. Several of the menus are multi-step. In some situations if an adjustment is made, additional options become available for further adjustment. Examples of these multi-step menus are Depth Range, Depth Alarm and Zoom. See the detailed description of each function for further explanation.
MENU FUNCTIONS Senstivity The Sensitivity function controls the sensitivity of the sonar receiver. The Wide 128 automatically adjusts the level of receiver sensitivity based on a number of factors including the depth of the water and the level of noise present. Noise can be caused by other electronic devices, engines, trolling motors, propeller cavitation and hydrodynamic flow among others. The user has the option of biasing this Sensitivity adjustment either higher or lower based on personal preference. You can select one of 11 sensitivity bias settings from -5 to +5. A bias setting of 0 (Factory Setting) has no effect on the automatic sensitivity control. Increasing the bias (+1 through +5) causes the unit to display the information from progressively smaller sonar returns. By decreasing the sensitivity bias (-1 through -5), the unit effectively filters small sonar returns. In murky or muddy water, it is often advantageous to reduce the sensitivity bias. This prevents the display from being cluttered with sonar returns from debris or suspended particles. In very clear or very deep water, it may be desirable to increase the sensitivity bias since even the smallest sonar return may be of interest to the user.

To adjust Sensitivity, press MENU repeatedly until the Sensitivity heading is displayed. When the Sensitivity menu appears, use the UP ARROW to increase the sensitivity bias, or the DOWN ARROW to reduce sensitivity bias. By holding either ARROW button depressed, the unit will sequence through the available settings until you release the button or the end of the adjustment range is reached. If additional time is needed to study a menu, press and hold the MENU button and the menu will remain on-screen indefinitely. If a setting limit is reached, the ARROW symbol attached to the menu appears to be hollow which indicates that the related button has no further function. Also, the audible "error" consisting of multiple chirps will be heard. After an adjustment is made, the menu disappears and the new sensitivity setting begins to affect new sonar information as it flows on-screen. If additional adjustment is needed, the UP ARROW or DOWN ARROW can be pressed without having to first press MENU.
Depth Range The Depth Range function controls the vertical distance displayed on the graphic area of the display. There are 9 different depth ranges available. The top of the range is always 0, or the surface of the water. Ranges of 0-15', 0-30', 0-60', 0-120', 0-180' , 0-240' , 0-360' , 0-480' , and 0-600' are available. The range which positions the bottom depiction closest to the bottom of the graphic area of the display, will best utilize the available display resolution. The Wide 128 automatically adjusts the depth range depending on the depth of the water. The unit tries to maintain the bottom depiction about 2/3 down the total range (for example, in 20' of water, the 0-30' range would be selected). This provides the best display resolution and therefore the best target separation possible. The Depth Range can be adjusted manually. Press MENU repeatedly until the Depth Range menu is visible. The two options available are "Auto" (Factory Setting) and "Manual". Pressing the DOWN ARROW enables "Manual" depth range control and an additional menu will appear which allows the user to adjust the current depth range setting. If no further button is pressed, the current depth range is selected as the desired range and the unit returns to normal operation. Using "Manual" Depth Range control, the user can view sonar information from the area near the surface in great detail. If a depth range other than the current range is desired, pressing the DOWN ARROW to highlight "Adjust" will allow selection of one of the 9 available ranges. Simply press and hold the UP or DOWN ARROW button to scan through the available options. If a setting limit is reached, the audible "error" or multiple chirps will be heard and no further adjustment is allowed. When "Manual" range is used, the unit no longer adjusts the Depth Range to the most appropriate range for bottom display. Often, the bottom may not be visible on-screen. The digital depth readout always determines the depth of the bottom, even if it is not visible on-screen. When a Depth Range is selected manually and the Depth Range menu is still active (most recently used), further adjustment of the depth range can be achieved by simply pressing the appropriate UP or DOWN ARROW button. The button press will bring the Depth Range menu on-screen and allows immediate adjustment of the range. To return to "Automatic" Depth Range control, press the MENU button until the Depth Range menu appears on-screen and use the UP ARROW to select AUTO. The Wide 128 returns to Automatic operation.

Zoom Zoom is similar to Depth Range in that it controls the range of information displayed in the graphics area of the display. Zoom, however, allows selection of ranges beneath the surface so any area of water between the surface and the bottom can be enlarged to provide more detailed information. By using the full display to show a small area of coverage, the effective display resolution is increased, and the unit's ability to separate targets which are very close together is enhanced. There are four different Zoom ranges available; 7 1/2', 15', 30', and 60'. These ranges are not directly user controlled but are instead dependent on the current depth range. In shallow water, when the 15' or 30' range is in use, the Zoom range is 7 1/2'. If the 60' or 120' range is in use, the Zoom range is 15', if a 180'-480' depth range is in use, the Zoom range is 30', and if the 600' range is in use, the Zoom range is 60'. The Wide 128 shows Zoom range in conjunction with the full depth range. The Zoom range is shown on the left side of the screen and full range information is shown on the right side of the display. Zoom can either operate automatically, in which the Zoom range is constantly adjusted to show the bottom, or manually, in which the user controls the location of the Zoom range. "Automatic" Zoom is especially helpful when looking for structure or bottom detail. The "Automatic" Zoom keeps the bottom in view even in quickly changing terrain. "Manual" Zoom provi des detailed information of any area from the surface to the bottom. In "Manual" Zoom, the Zoom range does not move as the terrain changes. To operate Zoom, Press MENU repeatedly until the Zoom menu is onscreen. Three options are available: "Off" (Factory Setting), "Auto" (Automatic bottom tracking Zoom), and "Manual" (User controlled Zoom range). Press the DOWN ARROW once to highlight Auto. When the menu disappears, the graphics area of the screen will be divided in half. Full range information on the right, Zoom information on the left. The digital depth readout is unaffected by Zoom. Pressing the DOWN ARROW again to highlight "Manual" activates Manual Zoom. The menu further expands to show the current Zoom range, and allows user adjustment of this range. When the range is shown in the menu, the upper number represents the top of the current Zoom range. The lower number represents the bottom of the Zoom range. The UP and DOWN ARROW buttons can be used to move this range. The upper number can never be less than 0 (the surface of the water), and the lower number can never be greater than the active depth range. The difference between the two numbers (the Zoom range) is preset and determined by the active depth range. Once "Manual" Zoom is selected, the display will appear the same as in "Auto" Zoom, but the zoom range does not change automatically. If further adjustment of the zoom range is necessary, pressing either ARROW button while Zoom is active will move the Zoom range up or down. The Menu returns briefly to show the numeric values as the adjustment is made. To disable Zoom, press the MENU button until the Zoom menu is on-screen. Use the UP ARROW to highlight Off, and let the menu time out. When the unit is powered off, the Zoom menu returns to Zoom Off.

Fish ID The Fish ID menu controls the method used to portray fish. There are three selections available: ID Off, ID On, ID+. The factory setting is ID+. With ID Off, sonar returns are displayed as "raw" information. There is no interpretation made by the unit. Selecting ID Off will also disable the Fish Alarm if selected.
ID On enables the Wide 128 to interpret the raw sonar data and using a variety of techniques, depicts appropriate returns as one of three different size fish symbols. Use the arrow buttons to highlight the desired setting.
USING DIAGNOSTIC The Wide 128 contains a powerful diagnostic tool which can aid in determining the cause of a problem. To enable Diagnostic, power the unit on and use the DOWN ARROW button to highlight the Diagnostic option on the initial screen. Diagnostic can only be accessed at power-up. After the menu times out, the first of two diagnostic screens will appear. Upon enabling diagnostic, the Wide 128 will perform a self-test. This test confirms the operation of all internal circuitry. At the conclusion of the test, one of two messages will appear; "passed" indicates that the internal test discovered no failures. "Failed" indicates that a significant internal problem was discovered and the unit will require factory service. In conjunction with the failed indication will be a code which indicates to the repair personnel where the problem is. Press MENU to advance to the second Diagnostic screen. The second Diagnostic screen shows transducer connection and voltage input. The voltage input category is especially helpful in diagnosing input voltage problems. The current input voltage will be displayed. If voltage fluctuations or power supply in excess of 16 VDC or less than 10 DC is suspected, use the diagnostic screen to confirm input voltage. Often, small outboard motors do not effectively regulate voltage when operated at high engine speeds. Use Diagnostic while running the boat at high speeds to show the voltage gain. Also, if you are using the Wide 128 in portable configuration or from the trolling motor battery, Diagnostic can be used to evaluate the health of the battery by showing the current voltage.
