Showing AIS Vessels on the Radar Screen
AIS requires the use of an external AIS device and active transponder signals from other vessels.
You can congure how other vessels appear on the Radar screen. If any setting (except the AIS display range)
is congured for one radar mode, the setting is applied to every other radar mode. The details and projected
heading settings congured for one radar mode are applied to every other radar mode and to the Radar
Overlay.

VRM and EBL
The variable range marker (VRM) and the electronic bearing line (EBL) measure the distance and bearing
from your boat to a target object. On the Radar screen, the VRM appears as a circle that is centered on the
present location of your boat, and the EBL appears as a line that begins at the present location of your boat and
intersects the VRM. The point of intersection is the target of the VRM and the EBL.
Showing the VRM and the EBL
The VRM and the EBL congured for one mode are applied to all other radar modes.
