NOTE:

You can optimize the radar display for each radar mode.

Select a radar range (Adjusting the Radar Range,

page

24).

Restore the default value of the gain setting (Adjusting Gain

on the Radar Screen Automatically, page 27).

Adjust the gain setting manually (Adjusting Gain on the

Radar Screen Manually, page 27).

Radar Gain and Clutter

Adjusting Gain on the Radar Screen Automatically

The automatic gain setting for each radar mode is optimized for

that mode, and may differ from the automatic gain setting used

for another mode.

NOTE:

Depending upon the radar in use, the gain 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

Gain

Select an option:

• To adjust the gain automatically for changing conditions,

select

Auto Low or Auto High.

• To adjust the gain automatically to show birds over the

surface of the water, select Auto Bird.

Adjusting Gain on the Radar Screen Manually

For optimal radar performance, you can manually adjust the

gain.

NOTE:

Depending upon the radar in use, the gain 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

Gain

Select

Up to raise the gain, until light speckles appear across

the Radar screen.

Data on the Radar screen is refreshed every few seconds. As

a result, the effects of manually adjusting the gain may not

appear instantly. Adjust the gain slowly.

Select Down to lower the gain until the speckles disappear.

If boats, land, or other targets are within range, select Down

to lower the gain until the targets begin to blink.

Select Up

to raise the gain until the boats, land, or other

targets appear steadily lit on the Radar screen.

Minimize the appearance of nearby large objects, if

necessary.

Minimize the appearance of side-lobe echoes, if necessary.

Minimizing Nearby Large-Object Interference

Nearby targets of significant size, such as jetty walls, can cause

a very bright image of the target to appear on the Radar screen.

This image can obscure smaller targets located near it.

NOTE: Depending upon the radar in use, the gain 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 >

Radar Menu

> Gain

Select

Down to lower the gain until the smaller targets are

clearly visible on the Radar screen.

Reducing the gain to eliminate nearby large-object

interference may cause smaller or distant targets to blink or

disappear from the Radar screen.

Minimizing Side-Lobe Interference on the Radar Screen

Side-lobe interference may appear to streak outward from a

target in a semi-circular pattern. Side-lobe effects can be

avoided by reducing the gain or reducing the radar range.

NOTE:

Depending upon the radar in use, the gain 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

Radar Menu > Gain

Select

Down to lower the gain until the semi-circular,

streaked pattern disappears from the Radar screen.

Reducing the gain to eliminate side-lobe interference may

cause smaller or distant targets to blink or disappear from the

Radar screen.

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

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

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 (Tips

and Shortcuts

, page

1).

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, select MENU > Radar Options >

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.
