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.

Incoming Distress Calls
If your compatible 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.

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 0183, you can track vessels that send position
reports.
This feature is also available with NMEA 2000, when the
vessel sends the correct PGN data (PGN 129808; DSC
Call Information).
Every position report call received is logged in the DSC list
(
).
