A message banner appears and an alarm 

sounds when an AIS-activated vessel en-

ters the safe-zone area around your boat. 

The object is also labeled as dangerous 

on the screen. When the alarm is off, the 

message banner and audible alarm are 

disabled, but the object is still labeled as 

dangerous on the screen.

  Select a time at which the alarm will 

sound if a target is determined to inter-

sect the safe zone. 

For example, to be notified of a pending 

intersection 10 minutes before it will likely 

occur, set Time To to 10, and the alarm 

will sound 10 minutes before the vessel 

intersects the safe zone.

AIS Distress Signals

Self-contained AIS distress signal devices 

transmit emergency position reports when 

activated. The chartplotter can receive 

signals from Search and Rescue Transmit-

ters (SART), Emergency Position Indicating 

Radio Beacons (EPIRB), and other man 

overboard signals. Distress signal transmis-

sions are different than standard AIS trans-

missions, so they appear differently on the 

chartplotter. Instead of tracking a distress 

signal transmission for collision avoidance, 

you track a distress signal transmission to 

locate and assist a vessel or person.

Navigating to a Distress Signal Transmission

When you receive a distress signal transmis-

sion, a distress signal alarm appears.
