Incoming Distress Calls
If your Garmin chartplotter and VHF radio are connected using NMEA 0183 or NMEA 2000, your
chartplotter alerts you when your VHF radio receives a DSC distress call. If position information
was sent with the distress call, that information is also available and recorded with the call.
The symbol designates a distress call in the DSC list and marks the position of the vessel on the
Navigation chart at the time when the DSC distress call was sent.

Man-Overboard Distress Calls Initiated from a VHF Radio
When your Garmin chartplotter is connected to a Garmin NMEA 2000-compatible radio, and
you initiate a man-overboard DSC distress call from your radio, your Garmin chartplotter shows
the man-overboard screen and prompts you to navigate to the man-overboard point. If you have
a Garmin autopilot system connected to the network, your chartplotter prompts you to start a
Williamson’s turn to the man-overboard point.
If you cancel the man-overboard distress call on the radio, the chartplotter screen prompting you to
activate navigation to the man-overboard location disappears.
