Conguring Other Vessels
To congure settings for boats other than your own, from the
Home screen, select Congure > Other Vessels.
NOTE: To congure AIS or DSC information for other boats, your
unit must be connected to an external AIS or DSC device.

and speed for boats that are within range and equipped with a
transponder.
DSC

used for collision avoidance, and the zone can be customized.
To customize safe-zone settings:
From the Home screen, select Congure > Other Vessels > AIS
Alarm.
Range—change the measured radius of the safe-zone ring to
a specied distance from 500 ft. to 2.0 nm (or from 150 m to
3.0 km, or from 500 ft. to 2.0 mi).
Time to (Safe Zone)—sounds an alarm if AIS or MARPA
determines that a target will intersect the safe zone within the
dened time interval (from 1 to 24 minutes).
