Setting the Safe-zone Collision Alarm
The safe-zone collision alarm is used only with AIS and MARPA. MARPA functionality works with radar
(page 68). 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.
 The safe-zone collision alarm is automatically set to  every time you turn your chartplotter on.

A message banner appears and an alarm sounds when a MARPA-tagged object or an AIS-activated vessel
enters the safe-zone ring around your boat. The object is also labeled as dangerous on the screen. The 
setting disables the message banner and the audible alarm, but the object is still labeled as dangerous on the
screen.

(or from 150 m to 3.0 km, or from 500 ft. to 2.0 mi.).
3. Select a distance.
4. Select  to sound an alarm if AIS or MARPA determines that a target will intersect the safe zone
within the dened time interval (ranging from 1 to 24 minutes).
