Rain Clutter

Precipitation reflects radar signals, cluttering the screen. Interference Rejection reduces or eliminates returns caused by rain, hail, sleet or snow.

Interference Rejection

Reduces interference from other active radars near your vessel. If another ship is operating radar near you, interference from its radar signals can appear on your dis- play. Increase interference rejection until radar interference is eliminated from your display. Interference Rejection has four settings: Off, Low, Medium and High.

Target Boost (only available on some radars)

This feature increases the size of radar targets, making them easier to see on the display. Target Boost has four options: Off, Low, Medium and High.

Clear Trails

Clears all target trails from the radar screen. New trails will continue to appear unless you turn off the target trails feature.

To Clear Trails:

1.Press the Menu key, the Radar menu will appear.

2.Use the Arrow keypad to select Clear Trails and press ENTER.
