adjusting. If the digital depth readout is w orking but there is no bottom
visible on-screen, it is possible the depth range has been adjusted manually
to a range low er than w hat is needed to display the bottom. Also, in very
deep w ater, it may be necessary to manually increase the G

If you are using a transducer sw itch to connect tw o transducers to the
ensure the sw itch is in the correct position to connect a transducer that is
in w ater. (If a trolling motor transducer is selected and the trolling motor is
out of w ater, no sonar information appears.)
If none of the above solve the problem, inspect the transducer cable from
end to end for breaks, kinks, or cuts in the outer casing of the cable. If the
transducer is connected to the unit through a sw itch, temporarily connect
it directly to the unit and try again. If none of these items identifies an
obvious problem, the transducer itself may be the problem. Be sure to
include the transducer if returning the unit for repair.

inconsistent digital depth indication.

5. The unit comes on before I press POWER, and w on't turn off.
Check the transducer cable—if the outer jacket of the cable has been cut
and the cable is in contact w ith bare metal, you need to repair the cut w ith
electrical tape. If there is no problem w ith the cable, disconnect the
transducer from the unit and see if the problem is corrected, to confirm the
source of the problem.
6. I get gaps in the reading at high speeds.
Your transducer needs adjusting. If the transducer is transom-mounted,
there are tw o adjustments available to you—height, and running angle.
M ake small adjustments and run the boat at high speeds to determine the
effect. It may take several tries to optimize high speed operation. This can
also be a result of air or turbulence in the transducer location caused by
rivets, ribs, etc.
