Using the ROCKER and the SELECT keys, follow the screens to configure your chartplotter. Testing the Optional Transducer Installation Because water is necessary to carry the sonar signal from the sounder, the transducer must be in the water to work properly. You cannot get a depth or distance reading when the transducer is out of the water. When you place your boat in the water, check for leaks around any screw holes that were added below the water line. Do not leave your boat in the water for an extended period of time without checking for leaks. GPSMAP 400/500 Series Installation Instructions
