Unit turns on but will not read bottom:
• Transducer may not be properly leveled or connected. Check cable connec-
tions. Make sure the bottom of the transducer has a clear path to the
bottom, and is not obstructed by any solid objects.
• Check to see if you have adjusted the manual depth range. If range is set
shallower than the depth of the water, bottom will not display in the viewing
area. Adjust range to be just slightly deeper than bottom.
Screen seems to be getting heavy interference, with lots of “clutter”:
• Adjust the Showdown 5.6 Dual Beam sensitivity. Often, decreasing the unit’s
sensitivity will keep unwanted signals from appearing on screen.
• You might be receiving interference from adjacent electronic devices, such
as a competing sonar unit. Activate and adjust the ShowDown’s Noise
Rejection until you find a level that clears up most or all of the interference
(see NOISE section).
