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.

From a radar screen or the radar overlay, select MENU >

Noise Rejection > Sea Clutter.

Select Presets or Auto.

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 Sea Clutter on the Radar Screen Manually

You can adjust the appearance of clutter caused by choppy sea

conditions. The sea clutter setting affects the appearance of

nearby clutter and targets more than it affects the appearance of

distant clutter and targets. A higher sea clutter setting reduces

the appearance of clutter caused by nearby waves, but it can

also reduce or eliminate the appearance of nearby targets.

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.

From a radar screen or the radar overlay, select MENU >

Noise Rejection > Sea Clutter.

Select Up or Down to adjust the appearance of sea clutter

until other targets are clearly visible on the radar screen.

Clutter caused by sea conditions may still be visible.

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

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.

From a Radar screen or the Radar overlay, select MENU >

Noise Rejection > Rain Clutter.

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 > Crosstalk Rej..

Echo Trails

The echo trails feature enables you to track the movement of

vessels on the radar display. You can change the length of time

the trail is displayed.

NOTE: Depending upon the radar in use, the settings configured

for use in one radar mode may or may not be applied to other

radar modes or to the radar overlay.

distances on the radar screen.

Nav Lines: Shows the navigation lines that indicate the course

you have set using Route To, Auto Guidance, or Go To.

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.

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.

Using a magnetic compass, take an optical bearing of a

stationary target located within viewable range.

Measure the target bearing on the radar.

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

mode is applied to every other radar mode and to the Radar

overlay.

From a Radar screen or the Radar overlay, select MENU >

Radar Setup > Front of Boat.
