1.10 How to Reject Interference
Interference from other acoustic equipment operating nearby or other electronic
equipment on your boat may show itself on the display as shown in the figure below.
When this occurs use the interference rejector.

(small targets).

1. Click the [Sounder] icon ( ) from the InstantAccess bar™ to show the [Sounder]
menu, then click the [Interference] icon ( ). [INTERFERENCE] appears in the
miscellaneous section of the header and is highlighted in a green color.
2. Scroll to adjust the level of interference rejection, referring to the table below.
