Configuring Other Vessels
To configure settings for boats other than your own, from the Home screen,
select Configure > Other Vessels.
NOTE: To configure AIS or DSC information for other boats, your unit must
be connected to an external AIS or DSC device.
aiS—turn AIS (Automatic Identification System) on or off. AIS alerts you to
area traffic by providing boat IDs, position, course, and speed for boats that are
within range and equipped with a transponder.
dSC—turn DSC (Digital Selective Calling) on or off.
aiS alarm—create a safe zone around your boat for collision avoidance. The
zone can be customized.
To customize safe-zone settings:
From the Home screen, select Configure > Other Vessels > aiS alarm.
• Range—change 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).
• Time to (Safe Zone)—sounds an alarm if AIS or MARPA determines
that a target will intersect the safe zone within the defined time interval
(from 1 to 24 minutes).
• aiS alarm—when On is selected, a message is displayed (“AIS:
Dangerous Target”) when a vessel enters the safe zone. When Off is
selected, the message will not be displayed.
