User manual HUMMINBIRD LCR 3D

[. . . ] 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. [. . . ] Also, care should be exercised when removing the cables from the unit. Grip the cable on the head when removing. Cables can be damaged if they are removed by pulling the wires. ACCESSORIES The Trolling Motor Mount adapter, which mounts the sensor on the foot of a trolling motor, gives excellent readings with no interference from the electric motor. Please note, however, that the LCR 3D area of coverage is not round, but elongated side to side. As a result, the display can become disorienting when the trolling motor is turned. Remember that terrain shown on the left of the LCR 3D screen is to the left of the transducer, not necessarily left of the boat. Item Trolling motor adapter plate Part # AD-STM-7 Humminbird also offers the following accessories. Note that, for installation on a larger boat where the transducer is located well away from the LCR 3D, you may need to purchase the 10' sensor extension cable before beginning installation. Other accessories enhance the performance and capabilities of your LCR 3D, and can be added at any time. For more information on these accessories, contact your local Humminbird dealer or call our tollfree Customer Service Hotline, listed inside the back cover. Item 10' cable Swivel Base Video Part No. EC-9 SM-LCR VID-1 Use Extends transducer cable Allows unit to swivel 360° Complete Guide to Humminbird Depth Sounders - VHS TESTING THE INSTALLATION After installing your transducer, LCR 3D, and cables, you should test the installation. Testing should be performed on the water, since that is the only way to check your sensor's performance. With your boat at idle, press the POWER button to turn the unit on. The LCR 3D performs a self-test on its electronics, then automatically selects the right depth range and sensitivity level for conditions. Momentarily, you'll see the reading start to "march" across the screen from right to left and a digital depth readout in the upper right corner. Increase your boat speed to ensure that you get a continuous bottom reading as the boat moves. Your sensor is designed to operate at up to 75 mph, however exercise caution when operating any boat at high speed. If the LCR 3D performs well at idle or slow speeds, but the display is not continuous at higher speeds, the sensor is not installed properly. Air bubbles or turbulence from the boat hull are passing across the sensor face, blocking the transmitted signal. By following the instructions in "Mounting the Sensor, " 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 and speak with one of our highly trained customer service representatives.
