6.11 How to Reduce Radar Interference
Radar interference can occur when your vessel is near the radar of another vessel that
operates on the same frequency band with your radar. The interference shows on the
screen in many bright dots. The dots can be random or in the shape of dotted lines
that run from the center to the edge of the display. You can identify the interference
from the normal echoes, because the interference does not appear in the same loca-
tion at the next rotation of the antenna.
Turn off the interference rejector when there is no interference to prevent the loss of
weak targets.
To use the interference rejector
1. Long-push the RotoKey.
2. Use the RotoKey to select [Filters] followed by [Int Reject].
3. Push the RotoKey to activate or deactivate the interference rejector.
