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.

AIS Distress Signal Device Targeting Symbols

Symbol Description
AIS distress signal device transmission. Select to see more
information about the transmission and begin navigation.

Transmission test. Appears when a vessel initiates a test of
their distress signal device, and does not represent a true
emergency.
Transmission test lost.

Enabling AIS Transmission Test Alerts

To avoid a large number of test alerts and symbols in crowded
areas such as marinas, you can select to receive or ignore AIS
test messages. To test an AIS emergency device, you must
enable the chartplotter to receive test alerts.
