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.
Select Review > Go To to begin navigation to the
transmission.
