While it is possible to perform some checks with the boat trail-
ered, the boat should be in the water to properly test the installation .
Press the
P
button and the Fishfinder 240 should power on.
If the unit fails to power on, verify that the wiring adapter is seat-
ed 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 sup-
ply that exceeds 16 VDC, a Battery Voltage High warning (see
page 38) 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 con-
nected 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 opera-
tion 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 boats
performance and place the transducer at greater risk
of striking underwater objects.
