7.7 How to Reduce Interference
Interference from other fish finders and electrical equipment appears on the screen as
shown in the illustration. When these types of interference appear on the screen, use
the interference rejector to reduce the interference. Turn off the interference rejector
when there is no interference, so that you do not erase weak echoes.
1. Open the home screen, then tap [Settings] - [Sounder].
2. Turn on [Interference Rejection].
3. Tap [Low], [Medium], [High] or [Auto]. [High] provides the greatest interference re-
jection. [Auto] automatically selects suitable interference setting.
4. Tap the close button to finish.
To deactivate the interference rejection, tap [Off] at step 3.
