Adjusting Sea Clutter on the Radar Screen Automatically
You can set the chartplotter to automatically adjust the
appearance of clutter caused by choppy sea conditions.
NOTE: Depending upon the radar in use, the sea clutter setting
configured for use in one radar mode may or may not be applied
to other radar modes or to the radar overlay.
NOTE: Not all options and settings are available on all radar and
chartplotter models.
1
From a radar screen or the radar overlay, select MENU >
Noise Rejection > Sea Clutter .
2
Select Presets or Auto .
3
Select a setting that reflects the present sea conditions.
When using a compatible radar model, the chartplotter adjusts
the sea clutter based on the sea conditions automatically.
Adjusting Rain Clutter on the Radar Screen
You can adjust the appearance of clutter caused by rain.
Reducing the radar range also can minimize rain clutter
( Adjusting the Zoom Scale on the Radar Screen , page 18 ).
The rain clutter setting affects the appearance of nearby rain
clutter and targets more than it affects the appearance of distant
rain clutter and targets. A higher rain clutter setting reduces the
appearance of clutter caused by nearby rain, but it can also
reduce or eliminate the appearance of nearby targets.
NOTE: Depending upon the radar in use, the rain clutter settings
configured for use in one radar mode may or may not be applied
to other radar modes or to the Radar overlay.
1
From a Radar screen or the Radar overlay, select MENU >
Noise Rejection > Rain Clutter .
2 Select Up or Down to decrease or increase the appearance
of nearby rain clutter until other targets are clearly visible on
the Radar screen.
Clutter caused by rain may still be visible.
Reducing Cross Talk Clutter on the Radar Screen
You can reduce the appearance of clutter caused by
interference from another nearby radar source, when the cross
talk reject setting is on.
NOTE: Depending upon the radar in use, the cross talk reject
setting configured for use in one radar mode may or may not be
applied to other radar modes or to the Radar overlay.
From a Radar screen or the Radar overlay, select MENU >
Noise Rejection > Cross Talk Reject .

Measuring the Potential Front-of-Boat Offset
The front-of-boat offset compensates for the physical location of
the radar scanner on a boat, if the radar scanner does not align
with the bow-stern axis.
1
Using a magnetic compass, take an optical bearing of a
stationary target located within viewable range.
2
Measure the target bearing on the radar.
3
If the bearing deviation is more than +/- 1°, set the front-of-
boat offset.
Setting the Front-of-Boat Offset
Before you can set the front-of-boat offset, you must measure
the potential front-of-boat offset.
The front-of-boat offset setting configured for use in one radar
