Configuring Other Boats

To configure settings for boats other than your own, from the Home
screen, select Configure > Other
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 equipped with a transponder within range.
DSC—turn DSC (Digital Selective Calling) on or off.
NOTE: To configure AIS or DSC information for other boats,
your unit must be connected to an external AIS or DSC device.

boats.
Safe Zone—turn a safe zone around your boat on or off. This is
used for collision avoidance, and can be customized:
• Ring—show or hide a ring on the map showing the safe zone
for your boat.
• Range—change the measured radius of the safe zone ring to a
specified distance from 0.1 to 2.0 nm (or .02 to 5.0 km, or 0.1
to 2.0 mi).
• Time to Safe Zone—sounds an alarm if AIS determines that
a target will intersect the Safe Zone within the defined time
interval (ranging from 3 to 24 minutes).
