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.

HOW SONAR WORKS Your Humminbird unit uses sonar to locate and define underwater objects, define the bottom terrain, as well as determine distance. Sonar technology is based on sound waves. Your Humminbird unit sends out a sound wave signal. With this signal it determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off an object. Your Humminbird uses the reflected signal to interpret location, size and composition of an object. Sonar is very fast. A sound wave can travel from the surface to a depth of 240' (70m) and back again in less than 1/4 of a second. It is unlikely that your boat can "outrun" this sonar signal. The 100SX is a 200kHz, single-beam fishfinder. The 200 kHz frequency provides excellent sonar resolution (the ability to distinguish small returns or returns which are close to the bottom), while providing depth capabilities to 600' (185m). The shape of the sonar beam is symmetrical and covers an area of approximately 24 degrees side to side and front to rear. Actual depth capability depends on factors such as bottom hardness, water conditions, and transducer installation. Units will typically read to deeper depths in fresh water than in salt water
SIMULATOR OPERATION The 100SX 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 100SX. 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 powerup 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 100SX 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 100SX for your particular operation. To exit Simulator mode, power the unit off. WHAT YOU SEE ON-SCREEN Your 100SX uses a 128 x 64 matrix FSTN 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 on-screen 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

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 on-screen 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. 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 100SX 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. 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 100SX 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 100SX 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. 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 100SX will consume more power than with the backlight off. This is important when using the 100SX 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 100SX 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 on-screen 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 Menu 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 Sensitivity The Sensitivity function controls the sensitivity of the sonar receiver. The 100SX 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 onscreen 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 onscreen. 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', 0120', 0-180', 0-240', 0-360', 0-480', and 0600' are available. In the metric version, ranges of 0-5, 0-10, 0-20, 0-40, 0-60, 0-80, 0-110, 0-150, and 0-185 meters 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 100SX 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' (6m) of water, the 0-30' (0103) 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 100SX 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 Zoom ranges available: 7 1/2' (2m), 15' (5m), 30' (10m), and 60' (20m). These ranges are not directly user controlled but are instead dependent on the current depth range. In shallow water, when the 15' (5m) or 30' (10m) range is in use, the Zoom range is 7 1/2' (2m). If the 60' (20m) or 120' (40m) range is in use, the Zoom range is 15' (5m), if a 180'480' (60-150m) depth range is in use, the Zoom range is 30' (10m), and if the 600' (185m) range is in use, the Zoom range is 60' (20m). The 100SX 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 provides 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 divi ded 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.

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 100SX 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 100SX 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 100SX 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 I 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 VDC 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 100SX 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.
