Humminbird ICE 35 - Manual (Page 29)

NOISE REJECTION
Noise Rejection allows you to reduce cross-talk interference from
neighboring fishfinders that are operating on the same frequency as your
ICE Flasher Series™ Fishfinder.
If two nearby units are operating on the same frequency, your ICE Flasher Series™
Fishfinder display might show results from the neighboring fishfinder.
NOTE: Your other option is to use the Beam key to switch to a different operating
frequency (see Beam for more information).
1. Press the Noise key.
2. Turn the Selection dial to choose a particular noise rejection 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 Noise key or
turning the Selection dial, the noise 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 Noise Rejection.
