Man-Overboard Distress Calls Initiated from a VHF Radio
When the chartplotter is connected to a compatible VHF radio with NMEA 2000, and you initiate a man-
overboard DSC distress call from the radio, the chartplotter shows the man-overboard screen and prompts you
to navigate to the man-overboard point. If you have a compatible autopilot system connected to the network,
the 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 and SOS Distress Calls Initiated from the Chartplotter
When your chartplotter is connected to a Garmin NMEA 2000 compatible radio and you mark an SOS or
man-overboard location, the radio shows the Distress Call page so you can quickly initiate a distress call.
For information on placing distress calls from your radio, see the VHF radio owner’s manual. For information
about marking an MOB or SOS location, see
Marking a Man Overboard or Other SOS Location, page 48 .
