Radar 

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.

Before you can set the front-of-boat offset, you must measure the potential front-of-boat offset (see previous 

procedure).
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.
1.  From the Home screen, select Radar > Radar Setup > Front of Boat.
2.  Select and hold Up or Down to adjust the offset.

You can set whether vessel tracks appear on the Radar Overlay.

From the Home screen, select Charts > Radar overlay > Menu > Waypoints & Tracks > Tracks > on.

You can select the type of labels shown with waypoints on the Radar Overlay.
1.  From the Home screen, select Charts > Radar overlay > Menu > Waypoints & Tracks > Waypoint 

Display.

2.  Select a waypoint.

•  Select Symbol to identify waypoints using symbols.

AIS requires the use of an external AIS device and active transponder signals from other vessels. 
You can configure how other vessels appear on the Radar Overlay. The display range setting configured for the 

Radar Overlay is applied only to the Radar Overlay. The details and projected heading settings configured for 

the Radar Overlay are also applied to all radar modes.
1.  From the Home screen, select Charts > Radar overlay > Menu > other Vessels > AIS Display Setup.
2.  Complete an action:

•  Select AIS Display Range to indicate the distance from your location in which AIS vessels appear, and 

select a distance.

•  Select Details > Show to show details about AIS-activated vessels.
•  Select Proj. Heading to set the projected heading time for AIS-activated vessels, and select Done.
•  Select Trails to show the tracks of AIS vessels, and select the length of the track that appears using a 

trail.
