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.

Step Two - Connect the Power Cable to the Boat A 6 (2m) long power cable is included to supply power to the fishfinder. You may shorten or lengthen the cable using 18 gauge multi-stranded copper wire. CAUTION: Some boats have 24 or 36 volt electric systems. Be sure your unit is connected to a 12 VDC power supply. The Power can be connected to the boat's electrical system at two places: a fuse panel, usually located near the console, or directly to the battery. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on the fuse panel. Attach the black wire to ground, and the red wire to 12 VDC power (Figure 20). Be sure to use a one amp fuse in the connection. If you must wire the control head directly to a battery, be sure to install an inline fuse holder
CONTROL HEAD INSTALLATION and one amp fuse (not included) for the protection of the unit (Figure 21). Humminbird is not responsible for over voltage or over current failures. In order to minimize the potential for interference with other marine electronics a separate power source (such as a second battery) may be necessary. Step Three - Drill the Mounting Holes 1. Set the mounting bracket in place on the mounting surface. Mark the four mounting screw locations with a pencil or punch. 2. Set the mounting bracket aside, and drill the four mounting screw holes using a 9/64 (3.6mm) bit. Step Four - Run the Cables 1. If the cables must pass through a hole underneath the mounting surface, mark and drill a 1 (25mm) hole centered between the four mounting holes (Figure 22). Note: if the cables must pass through the mounting surface at a different location, drill the 1" (25mm) hole at that location and pass the cables through from underneath. Also, you must break out the tabs on the rear of the mounting base using needle nose pliers (Figures 24-25). 2. Insert all cables through the 1 (25mm) hole from beneath the mounting surface. 3. Pass the cables through the grommet (if the cable hole is underneath the mounting bracket) then press the grommet in place around the cables and into the 1 (25mm) hole. 4. Pass the cables through the mounting base, out the top of the mounting bracket. 5. Place the mounting bracket on the mounting surface aligned with the drilled holes. Insert the four flathead wood screws into the mounting holes and tighten fully (Figure 23). 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.

WHAT YOU SEE ON-SCREEN Your Wide Optic 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. The presentation of information on-screen may take one of several forms depending on the type of transducer being used, whether or not the Temp/Speed sensor is connected, and the current setting of various user options. See Advanced Operation for information on custom screen options. NOTE: When in simulator mode, the word "simulator" occasionally scrolls across the display indicating that the information onscreen is not real sonar data. The initial screen layout takes one of two basic forms depending on whether the Temp/Speed accessory is installed. Figure A shows the default view when the Temp/Speed accessory is not installed. The digital depth number shows the depth of 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 onscreen. 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 Onscreen Information). Figure B shows the default view when the Temp/Speed sensor is connected. Water surface temperature and boat speed are displayed at the lower right corner of the screen. If the Wide Optic determines that a Wide Side transducer is connected, the default view is shown in Figure C. Sonar information from both the left and right beams are shown. As you learn the many capabilities and user preference functions of the Wide Optic, additional screen configurations are possible. Figure D shows a view with "Small Digits" selected in the User Options menu. By selecting smaller digits for the depth, speed and temp information, more of the screen is available for the graphic representation of the sonar information. This effectively increases the display resolution of the Wide Optic, allowing targets which are very close together to be displayed as separate symbols.

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. When a sonar signal is reflected oft 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 Optic 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.
CONTROL FUNCTIONS The Wide Optic 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 Optic 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 Wide Optic will consume more power than with the backlight off. This is important when using the Wide Optic 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 Optic 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 onscreen 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. The one menu option which functions differently than previously described is the Options menu. User Options is a group of functions which are used initially to select user preferences. The Options are not normally needed during operation of the unit. Options differ from the other menu functions in that once selected for viewing, the menu will not "time out"-all the user options must be sequenced through before returning to normal operation. See User Options for detailed description.

MENU FUNCTIONS Sensitivity The Sensitivity function controls the sensitivity of the sonar receiver. The Wide Optic 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. The Sensitivity setting is remembered in memory after the unit is powered oft.

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 Optic 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 onscreen. 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 Optic returns to Automatic operation. Note: Depth Range is not remembered when the unit is powered off. At power up, the unit is always in automatic depth range.

Fish Alarm settings are remembered when the unit is powered off.
Triplog Triplog provides a running log of information based on input from the Temp/Speed sensor. Since Triplog requires information from the Temp/Speed sensor to operate, if this sensor is not detected by the Wide Optic, the Triplog menu will not appear as an option. To enable Triplog, press MENU repeatedly until the Triplog menu is onscreen. The Factory Setting is "Hide" which is selected. Use the DOWN ARROW to select "Show" and the fullscreen Triplog will appear. Triplog provides seven pieces of information; the current digital depth, water surface temperature, current boat speed, the distance traveled since the Wide Optic was powered up or reset, the average speed, the total time elapsed since power-up or reset, and the input voltage from your boat's electrical system. The time, speed, and distance calculations are useful for tracking your progress on a trip. The input voltage is useful for determining the condition of the charging system of the boat. When used in a portable application or whenever the Wide Optic is operated from a battery source, the voltage number can be used to determine battery life. The Wide Optic will operate at voltages from 10 to 16 VDC. Voltages in excess of 16 or less than 10 VDC will cause the unit to power off. Once Triplog is enabled, pressing MENU to bring the Triplog menu on-screen now shows an additional option, "Reset". By selecting Reset, the timer and distance log resets to 0 and the Triplog will begin to calculate elapsed time, distance traveled, and average speed from the time of reset. To disable Triplog, press the MENU button until the Triplog menu is on-screen. Use the UP ARROW to select Hide and let the menu time out. The Triplog continues to operate and log time and distance even when it is not visible onscreen. The Triplog resets at power off.
Options The Options Menu is actually a series of linked menu functions which are used initially to select user preferences. Once user preferences are selected, it is unlikely that these functions need to be accessed during the normal operation of the product. The Options menu works differently than other menu functions in that all of the options must be cycled through in order to return to normal operation. There are six Option menus: Units, Fish ID, Numeral size, Transducer, Display speed, and Reset. Press MENU until the Options menu is on-screen. There are two choices, Hide (Factory Setting) and Show. Use the DOWN ARROW to highlight Show and the first Options menu appears.

The Units function allows the user to select the units of measurement for the speed readout. Both MPH or statute miles per hour and KTS or nautical miles per hour are available. Use the ARROW buttons to highlight the desired selection. The Wide Optic remembers this selection even when the unit is powered off. Press MENU to go to the next menu.
Fish ID The next Option menu is Fish ID. There are three selections available; Off, ID On, and ID+ On. The factory setting is ID+ On. With Fish ID Off, sonar returns are displayed as "raw" information. There is no interpretation made by the unit. Selecting ID Off, also will disable the fish alarm. ID On enables the Wide Optic to interpret the raw sonar data and, using a variety of techniques, depict appropriate target returns as one of three different size fish symbols. Further identification shows whether the fish is in the left, center, or right beam. ID+ On adds an additional piece of information to the location of the fish. The depth beneath the surface for selected fish symbols is attached to the fish symbol.
Use the ARROW buttons to highlight the desired setting, and press MENU to advance to the next menu. The unit remembers Fish ID setting when powered off.
Numeral Size Numeral Size is the next Option menu. Two options are available: Big and Small. The factory setting is Big. With this setting, the digital depth and speed and temp numerals are drawn large enough to be readable from across the boat. The big numerals occupy space on the display which could be used for the graphics area. Hence, the small numerals option. With small numerals selected, a greater amount of the display area is available for the graphic view. This effectively increases the display resolution of the unit. Sonar targets which are very close together can often be displayed as separate targets, though the distance from which the numerals are readable is somewhat less. Use the UP and DOWN ARROW buttons to highlight the desired selection, then press MENU to advance to the next menu. Numeral Size settings are remembered when powered off.
Transducer The Transducer option allows manual selection or identification of a non-standard transducer. The Wide Optic is designed to work with the TriBeam transducer supplied with the unit. There are several instances in which an alternative transducer may be used (i.e. a Wide Side or a trolling motor mount transducer). Often two transducers are used in conjunction with a transducer switch to provide increased utility. The Wide Optic has the ability to positively identify a Tri-beam transducer. If this identification is made, the unit operates normally with no further input from the user. If a transducer other than the Tri-beam transducer is connected, the Wide Optic will assume this transducer is a Wide Side transducer (available as an accessory) and the screen layout will change automatically to show the Wide Side display. In the event that a non-standard transducer other than the Wide Side is connected (Dual Beam), the user must manually identify this transducer so that the Wide Optic can interpret the information received. Once this identification is made, the unit defaults to this setting whenever a nonstandard transducer is detected. The Transducer Option menu provides three options; Tri-beam, dual, and side. If a Tri-beam transducer is connected to the unit, the Tribeam selection is highlighted. It is not possible to select one of the other options. If a non-standard transducer is detected, an option other than Tri-beam is highlighted. If no previous user selection has been made, Side will be the default. If the Wide Side transducer is connected, then the proper selection has been made and no further user input is required. If a dual beam transducer is connected, use the ARROW buttons to highlight that selection. With dual selected, anytime the Wide Optic detects a transducer other than the standard Tri-beam, the unit will assume that transducer is a dual beam. Note: If a non-standard transducer is detected, it will not be possible to select the Tri-beam option in the Transducer Options menu. If a Tri-beam transducer is detected, only the Tri-beam selection is possible. Often it is desirable to use a transducer switch to connect two Tri-beam transducers or a Tri-beam transducer and a non-standard transducer to the Wide Optic. In either of these situations, the Wide Optic identifies the Tri-beam transducer and operates normally when that transducer is selected by the switch. If a non-standard transducer is selected by the switch, the Wide Optic will assume that transducer is of the type identified in the Transducer Options menu, and will configure the display accordingly.

USING DIAGNOSTIC The Wide Optic 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 powerup. After the menu times out, the first of two diagnostic screens will appear. Upon enabling diagnostic, the Wide Optic will perform a selftest. 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. Even if the self-test is passed, other messages may be present to indicate an abnormal situation. Examples of these are high-voltage and lowvoltage shut down indications. The Wide Optic will shut down to protect the inner circuitry if the input voltage exceeds 16 VDC or is less than 10 VDC. If either of these conditions cause the unit to shut down, a message will indicate this. NOTE: Powering the unit off will reset these messages. Press MENU to advance to the second Diagnostic screen.
The second Diagnostic screen evaluates external connections to the unit. The first category is Transducer input. If a transducer is detected, a message will indicate "connected". This is an excellent way to confirm transducer connection. If a transducer is connected directly to the unit, the connection will be indicated here. If a switch is used, use Diagnostic to confirm the connections from each transducer. If a series of dashed lines is shown, then no transducer is connected or there is a problem with the transducer or cable. The next categories indicate the connection of boat speed sensor and surface water temperature sensor. These accessory sensors can be purchased independently or together as a single sensor (see Available Accessories). If the sensors are connected and working properly, a "connected" message will appear. Note: This feature only works when the boat is in motion as the paddle wheel on the speed sensor must rotate to be detected. 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 Wide Optic 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. The total time category indicates the total time the unit has been in use since shipped from the factory. Note: It is normal for some hours to be indicated in the total time when the unit is new due to factory testing. While this is often of interest to the user, it is primarily a diagnostic tool for the repair technician should service be required. Press MENU again to exit Diagnostic.

USING ALTERNATIVE TRANSDUCERS The Wide Optic is designed to operate with the Tri-Beam transducer included standard with the product. The standard transducer can be mounted on the transom of the boat, or bonded to the inside of most fiberglass hulls. Tri-beam transducers are also available in trolling motor mounts, portable mounts, and bronze thru-hull type mounts. The Wide Optic also has the ability to work with the Wide Side Accessory Transducer. See Available Accessories for selection of the transducer.
Wide Side Operation The Wide Side transducer is a specialized "side-looking" transducer which is extremely useful for bank fishing or looking for bait fish in open water. The Wide Side transducer uses 3 different sonar elements which transmit signals to the left, right, and straight down from your boat. The downward beam is 200 kHz with a 24 degree area of coverage. This beam maintains a continuous digital depth readout from the bottom directly beneath your boat. The side beams are 455 kHz with a 16 degree area of coverage. The sidelooking elements can be used independently, or together to locate targets near the surface of the water on either side of your boat. The Wide Side transducer is available as a trolling motor mount, a transom mount, or a portable mount. Note: The Wide Side transducer can be connected directly to the Wide Optic or used in conjunction with the standard transducer through a transducer switch. When used with a switch in conjunction with the TriBeam transducer, the Wide Optic recognizes which transducer is connected whenever the switch position is changed. When a Wide Side transducer is connected, the screen display changes to display the information from the side-looking elements. There are four basic views available when the Wide Side transducer is in use: both, left, right, and down. These views are controlled by the View Menu, which is only present when operating in Wide Side mode. The default view is both, in which information from both the left and right elements are displayed on-screen. The digital depth of the water beneath your boat is always present. Viewing both left and right sides simultaneously gives you an excellent tool when searching for bait fish in open water, or when following a creek bed, however greater display resolution can be achieved by viewing only one side. To change the view, use the MENU button to bring the View menu onscreen. Use the ARROW buttons to select one of the four possible views. The Down view is similar to the traditional view when using the standard transducer, however there is no Tribeam information available such as fish location. When operating in Wide Side mode, the range must be adjusted manually, since the bottom is often not visible on-screen. Ranges of 15, 30, 60 and 120 feet are available. Also, Zoom is not possible in Wide Side mode, and the Zoom menu is not available. Experiment with the Wide Side transducer while operating it in a familiar area to learn how to maximize use of the information displayed. Remember that if you are using a trolling motor mount, the information displayed is controlled by the direction the trolling motor is pointing, not necessarily the direction the boat is traveling. To return to normal "down" operation using the Tri-beam transducer, simply change the switch setting if you are using in conjunction with a transducer switch, or reconnect the Tri-beam transducer. The Wide Optic will reconfigure the screen automatically.

WHAT YOU HAVE

The Humminbird Portable is available in several different configurations. You may have purchased the Portable case complete with a Humminbird fishfinder ready for operation. The Portable case is also available to adapt a Humminbird product you already own to portable operation. This manual serves for all applications and there may be minor differences in the hardware included depending on the configuration you purchased. The Humminbird Portable contains the portable case, a non-removable power cable, cable connector hardware kit, and a transducer mounting hardware kit. This kit contains everything necessary to adapt one of several different transducers to the portable (suction cup) mount. There are some parts included which may not be used depending on the type of transducer you have. Humminbird Portables are sold with Wide One Hundred, Wide 128, Wide Optic, and Wide Portrait fishfinders. Included are the portable case, a non-removable power cable, transducer mounting hardware, and the cable connector hardware kit. The type of transducer included varies with the fishfinder. This Operation Manual covers the assembly and operation of the Portable Case and transducer. Operation of the fishfinder is covered in the fishfinder Operation Manual. A phillips head screwdriver is required for installation. If you purchased a Portable Case with a fishfinder, additional mounting systems are available as accessories, which allow both a permanent mount and portable use of the same fishfinder. Refer to the Accessory catalog for ordering information.
INSTALLATION PORTABLE CASE ASSEMBLY Your new Humminbird Portable case incorporates a quick-disconnect mount and connector system for quick and easy removal of your Humminbird unit from he case. The mount allows the unit to tilt 90 degrees for easy viewing from any location. Open the Portable case and disconnect the cover from the base at the hinge point. If the Humminbird unit is included, pivot it forward and remove it from the Portable case by depressing the latch on the rear of the unit, and lifting the unit from the mount.
Remove the two battery compartment lids by lifting upwards on the front lip. Locate the connector hardware kit and the transducer hardware kit stored in the battery compartments. Refer to the illustration and route the transducer cable through the rear of the mount base. Insert the power and transducer cable into the connector holder. The slots for the connectors are keyed to prevent reversed installation, so be careful not to force the connector into the holder. The slots for the connections are keyed to prevent reversed installation, so be careful not to force the connector into the holder. If you are also using the Temp/Speed accessory (Wide Optic and Wide Portrait only), install that connector at this time also.
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.
Snap the support plate to the rear of the connector holder as shown in the illustration. Insert the connector holder assembly into place and use the two # 6-32 x 34 screws to fasten it to the mounting bracket.
Install the Humminbird unit by sliding it onto the mounting bracket until it is fully seated. All cable connections are made automatically.

INSTALLING THE BATTERIES

The Humminbird Portable unit is designed to use two 6-volt, lantern batteries with spring type terminals.
Any 6-volt lantern battery may be used: however for maximum battery life, we recommend using heavy-duty alkaline batteries. The Humminbird Accessory part number BAP allows you the use of 4 D cell batteries in place of the lantern battery. This allows the use of rechargeable type batteries to power the portable unit. Refer to the Humminbird Accessory catalog for more information. The actual life of a set of batteries can vary greatly depending on the type of battery and the ambient temperature. Wide units can operate 100 hours or move at an ambient temperature of 70 degrees. A decrease in ambient temperature will decrease the life of the battery. Refer to the diagram inside the battery compartments and install the batteries. Since different manufacturers make slightly different size batteries, it may be necessary to adjust the length of the spring contact to insure positive contact.

Re-install the battery covers by inserting the tab at the rear of the cover into the slot on the lower housing, and then snap the lid into place.
PORTABLE TRANSDUCER ASSEMBLY A suction cup mount and mounting bracket is included to adapt a transducer to portable operation. If you purchased the Portable case without the Humminbird unit, three types of mounting brackets are included to adapt your existing Humminbird transducer to portable operation.
Use the bracket, which fits your transducer, and refer to one of the three following illustrations for the appropriate assembly instructions. Parts have been included for both installation procedures, so there will be some parts remaining. If you choose to install the transducer permanently, additional hardware will be required. Call Humminbird Customer Support for more information. The wing nut allows you to adjust the angle of the transducer in the water so that it points straight down. Initial assembly of the suction cup requires the use of a phillips head screw driver. Installation and adjustment can be performed without the use of tools.
It is important that the transducer be mounted beneath the surface of the water, pointing straight down. The suction cup mount is designed for quick, easy installation and removal, not for highspeed operation. If you intend to operate your boat at any speed faster than trolling speeds, remove the suction cup transducer from the water. The transducer can cause damage or pull the portable unit into the water if it releases at high speed.
You can mount the transducer anywhere on the side of the boat if your boat remains stationary. If you are trolling, it is best to mount the transducer on the transom of the boat.
On fiberglass boats it is possible to place the transducer inside the hull of the boat in a pool of water. The sonar signal can pass through the hull of the boat with little signal loss. For ice fishing, Humminbird makes a special bracket to position the transducer at the right height and angle in the water.
USING THE HUMMINBIRD PORTABLE If you are using the suction cup transducer on a moving boat, it is best to secure the transducer cable in case of accidental release. A loose transducer can cause damage to itself, your boat, or become entangled in the propeller. Attach the tie-down strap to the transducer cable and loop the cable around an immovable object such as a rail or fitting as shown in the illustration.

When you have finished using the transducer, pivot the transducer body flat against the bracket and coil the cable around the assembly. The transducer and cable will fit into the center compartment of the Portable case for easy transport.
Pivot the Humminbird unit all the way down and reinstall the upper case. MAINTENANCE Your Humminbird Portable fishfinder is designed to provide years of trouble-free operation with virtually no maintenance. Follow the simple procedures below to ensure that your Humminbird Portable continues to deliver top performance. If you are storing the Portable case for an extended period of time, it is best to remove the batteries from the case in case of leakage. If the Portable case comes into contact with salt spray, simply wipe the affected surfaces with a cloth dampened in fresh water. Never leave your Humminbird Portable unit in a closed car or trunk- the extremely high temperatur4e generated in hot weather can damage the electronics.
Repairs should be performed only by authorized Humminbird technicians. HUMMINBIRD ONE YEAR FULL WARRANTY SERVICE POLICY. WARRANTY CUSTOMER SUPPORT
