Garmin 160 Manuale Utente

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 160 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 incre-
ments.  Placing the transducer too deep can adversely affect the boat’s performance 
and place the transducer at greater risk of striking underwater objects.
