Setting the Safe-zone Collision Alarm
The safe-zone collision alarm is used only with AIS. The safe zone is used for collision avoidance, and can be
customized. All safe-zone collision alarm settings are applied to all charts, to all 3D chart views, to all radar
modes, and to the Radar Overlay.
1. From the Home screen, select Configure > other Vessels > AIS Alarm > on.
A message banner appears and an alarm sounds when an AIS-activated vessel enters the safe-zone ring
around your boat. The object is also labeled as dangerous on the screen. The off setting disables the
message banner and the audible alarm, but the object is still labeled as dangerous on the screen.
2. Select Range to set the measured radius of the safe-zone ring to a specified distance from 500 ft. to 2.0 nm
(or from 150 m to 3.0 km, or from 500 ft. to 2.0 mi.).
3. Select a distance.
4. Select Time To to sound an alarm if AIS determines that a target will intersect the safe zone within the
defined time interval (ranging from 1 to 24 minutes).

Making a Call to an AIS Target

Perspective 3D
Perspective 3D provides a view from above and behind the boat (according to your course) and provides a
visual navigation aid. This view is helpful when navigating tricky shoals, reefs, bridges, or channels, and is
beneficial when trying to identify entry and exit routes in unfamiliar harbors or anchorages.
From the Home screen, select Charts > Perspective 3D.
