Testing the Installation
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 2-Amp fuse is installed and not blown. If the unit is
connected to a power supply that exceeds 18 VDC, a ‘Battery Voltage High’
warning will be displayed and the unit will turn off.
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.
