Testing The Installation - Garmin Fishfinder 100 BLUE Owner's Manual

Testing the Installation

While it is possible to perform some checks with the boat trailered, the
boat should be in the water to properly test the installation.
Press the Power button and the Fishfinder 100 Blue 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 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 and speed sensor installation, gradually increase
the boat' s speed while checking the unit operation. If the unit displays
intermittently or fails to display, verify that the transducer and speed sensor
are aligned parallel with the bottom. If necessary, adjust their heights until
the unit operates correctly. It may be necessary to make several adjustments
to ensure proper operation throughout the speed range. If the signals do
not improve, it may be necessary to move the transducer or speed sensor
to a different location.
When adjusting the depth of the transducer, make the adjustments in small
increments, no more than 1/8". Placing the transducer or speed sensor too
deep can adversely affect the boat's performance and increase the risk that they
may strike underwater objects.
