[. . . ] INSTALLATION PREPARATION PARTS SUPPLIED PARTS SUPPLIED Before installing your new Humminbird fishsinder, please ensure the following parts are included in the box: · · · · · Fishfinder Transducer with 20' (6m) of cable and mounting hardware kit Mounting system and mounting hardware kit 6' (2m) power cable Publications kit 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. [. . . ] The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy removal and installation (Figures 18-19). · · · 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 INSTALLATION 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. Set the mounting bracket aside, and drill the four mounting screw holes using a 9/64" (3. 6mm) bit. 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). Insert all cables through the 1" (25mm) hole from beneath the mounting surface. 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. Pass the cables through the mounting base, out the top of the mounting bracket. Place the mounting bracket on the mounting surface aligned with the drilled holes. [. . . ] While there is some variation in sonar characteristics of different species, typically the strength of the return is relative to the size of the fish. Zoom 6.
