Incoming Distress Calls
If your Garmin chartplotter and VHF radio are connected using
NMEA 0183, 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.
Navigating to a Vessel in Distress
The symbol designates a distress call in the DSC list and marks
the position of a vessel on the Navigation chart at the time the
distress call is sent.
