Humminbird ICE 35 - Manual (Page 28)

GAIN
Gain controls how much the return sonar signal is amplified; the
preferred setting depends on the conditions in the water under your
transducer. Increase the gain to see more of what is below the transducer, and
decrease the gain to reduce clutter on the screen. High gain levels should only be
necessary in deeper water or to see smaller objects.
1. Press the Gain key.
2. Turn the Selection dial to choose a particular gain setting, then press the
Selection dial to complete your selection.
NOTE: If you do not press the Selection dial within 5 seconds of pressing the Gain key or
turning the Selection dial, the gain select function will time out.
NOTE: If your control head beeps repeatedly as you turn the Selection dial, you have
reached the lowest or highest level possible for the Gain.
NOTE: If you turn the Selection dial without pressing a function key first, it will default to
the Gain function.
