Humminbird ICE 45, ICE 55, ICE 35 manual Gain

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.
