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.
Man-Overboard Distress Calls Initiated from the Chartplotter
When your Garmin chartplotter is connected to a Garmin NMEA 2000-compatible radio and you activate
navigation to a man-overboard location, the radio shows the Distress Call page so you can quickly initiate a
man-overboard distress call.
On the radio, press the DISTReSS key for at least three seconds to send the distress call.
For information on placing distress calls from your radio, see your Garmin VHF Radio Owner’s Manual. You
can mark an MOB and navigate to it ( page 27 ).
