[. . . ] TRANSDUCER MOUNTING PROCEDURE Humminbird's high-speed transducer is supplied with your LCR. This transducer has been designed to give good high speed readings on most all boat designs, including aluminum. Please carefully consider the following before installing your transducer. TRANSDUCER MOUNTING OPTIONS A. Transom Mount- The Humminbird high speed transducer allows the transducer element to be mounted below the bottom of the boat hull keeping the transducer out of turbulent water and insuring good high speed operation. [. . . ] Mount the bracket, using the mounting hardware supplied with your Dimension 3. (Note: Twist the bracket 90 degrees on the swivel base to access the mounting screws. ) 6. To connect the power cable to the 12-volt DC power source, wire the Dimension 3 through your fuse panel with a I-amp fuse (not included). If your boat does not have a fuse panel, you can wire the power cable to the battery with an in-line 1-amp fuse and fuse holder (not included) in the positive wire, as shown below. Attach the black lead to the negative (-) terminal, and wire the red lead through the fuse to the positive (+) terminal. NOTE: Do not use any power cable other than the one provided with your Dimension 3. Pull the transducer and power and accessory cables up through the 1" hole behind the gimbal bracket, and connect them to the back of the Dimension 3. To "dress" the I" hole and hold the cables securely, push excess cable into the hole, and install the hole cover provided with your unit. Loosen the mounting knobs and slip the Dimension 3 unit into the gimbal bracket. After installing your transducer, Dimension 3, and cables, you should test the installation. Testing should be performed on the water, since that is the only way to check your transducer's performance. The Dimension 3 performs a selftest on its electronics, then automatically selects the right depth range and sensitivity level for conditions. Momentarily, you"11 see the reading start to "march" across the screen from right to left and a digital depth readout in the lower right corner. Increase your boat speed to ensure that you get a continuous bottom reading as the boat moves. Your transducer is designed to operate at up to 75 mph, so feel free to test them at high speeds. If the Dimension 3 performs well at idle or slow speeds, but the display is not continuous at higher speeds, the transducer is not installed properly. Air bubbles or turbulence from the boat hull are passing across the transducer face, blocking the transmitted signal. By following the instructions in "Mounting the Transducer, " you can make simple adjustments that should fix the problem. NOTE: If other problems occur, see "Troubleshooting" later in this manual for tips from the Humminbird engineers. If you don't find the solution there, call our toll-free Customer Service Hotline. BASIC OPERATIONS This section explains how to run the Dimension 3 simulator for practice and how to start the Dimension 3 for actual use. You're also shown how to use the "screen control" buttons-the buttons that let you control the display of underwater images on the Dimension 3 screen. You should read this section and Section S, "Selecting Dimension 3 Functions, " as you first learn to use the Dimension 3. The remaining instructions can be followed while using the simulator or in actual operation. USING THE BUILT-IN SIMULATOR The Dimension 3 includes a built-in simulator that helps you learn to use your new equipment. [. . . ] Setting Display Speed; Factory setting: Maximum The Dimension 3 display is "updated" (advances across the screen) as you move through the water. The speed at which the display is updated depends on the Display Speed setting. To adjust it, select DISPLAY SPEED, and press the Up arrow for a faster setting or the Down arrow for a slower setting. In general, higher Display Speed settings provide faster updates, while slower Display Speeds provide more detailed information. [. . . ]
