DSC List
The DSC list is a log of the most recent DSC calls and other
DSC contacts you have entered. The DSC list can contain up to
100 entries. The DSC list shows the most recent call from a
boat. If a second call is received from the same boat, it replaces
the first call in the call list.
Viewing the DSC List
Before you can view the DSC list, the chartplotter must be
connected to a VHF radio that supports DSC.

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
Position Tracking
When you connect the chartplotter to a VHF radio using NMEA
