While it is possible to perform some checks with the boat trailered, to properly test the installation the boat should be in the water.
Press the Power button and the Fishfinder 100 should power on. If the unit fails to power on, verify that the wiring adapter is seated properly in the back of the unit, the Red and Black wires are connected to the correct polarity, and that the
As the unit powers on, it should immediately start showing the bottom. Verify that the unit is not in the simulator mode. If the unit is in the simulator mode, make sure that the transducer is connected to the wiring harness.
To test the transducer installation, gradually increase the boat speed while checking the unit operation. If the unit displays intermittently or fails to display, verify that the transducer is aligned parallel with the bottom and if necessary, adjust the transducer height until the unit operates correctly. It may be necessary to make several adjustments to ensure proper operation throughout the speed range.
When adjusting the depth of the transducer, make the adjustments in small increments. Placing the transducer too deep can adversely affect the boat’s performance and place the transducer at greater risk of striking underwater objects.
