AIS Distress Signals
Self-contained AIS distress signal devices transmit emergency position reports when activated. The chartplotter
can receive signals from Search and Rescue Transmitters (SART), Emergency Position Indicating Radio
Beacons (EPIRB), and other man overboard signals. Distress signal transmissions are different than standard
AIS transmissions, 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 transmission, a distress signal alarm appears.

alerts.
