March across the screen from right to left Increase your boat speed to ensure that you get a continuous bottom reading as the boat moves Your LCR 120 and its sensor are designed to operate at up to 75 mph so feel free to test them at very high speeds If the LCR 120 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 transmitting 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 Hummingbird engineers If you don t find the solution there call out Customer Service Hotline Section 4 Using the LCR 120 This section provides complete information on operating the LCR 120 through its front panel controls You are encouraged to read this information completely as you first learn to use the LCR 120 doing so will insure you make the most if its many features and functions The fist part of this section explains the use of the built in simulator which you can use to practice selecting functions through the front panel The remaining instructions which can be followed while using the simulator or in actual operation explain each function and are organized according to the front panel layout Using t2. will need the mounting template included with your manual In addition to the parts included you need the following for installation and operation e A powered hand drill and various drill bits e Philips and flat head screwdrivers e A ruler or measuring tape e Pen or pencil e 12 volt power source your boat s battery e A1 amp fuse e A fuse holder if you are wiring directly to the boat s battery e Silicone sealant for sealing drilled holes e 2 part slow cure epoxy for inside the hull transducer installations www reeischematic com 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 Thi
