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.
Select Info > DSC List.
Adding a DSC Contact
You can add a vessel to your DSC list. You can make calls to a
DSC contact from the chartplotter.
1 Select Info > DSC List > Add Contact.
2 Enter the Maritime Mobile Service Identity (MMSI) of the

3 Enter the name of the vessel.
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.

Man-Overboard Distress Calls Initiated from a VHF
Radio
When your 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 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.
For information on placing distress calls from your radio, see the
VHF radio owner’s manual. For information about marking an
MOB, see page 8 .
Position Tracking
When you connect your Garmin 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
( page 16 ).

dot indicates each previously reported position of a tracked
vessel, and a blue flag indicates the last reported position of the
vessel.

Individual Routine Calls
When you connect your Garmin chartplotter to a Garmin VHF
radio over the NMEA 2000 or the NMEA 0183 network, you can
use the chartplotter interface to set up an individual routine call.
When setting up an individual routine call from your chartplotter,
you can select the DSC channel on which you want to
communicate. The radio transmits this request with your call.
Selecting a DSC Channel
NOTE: The selection of a DSC channel is limited to those
channels that are available in all frequency bands. The default
channel is 72. If you select a different channel, the chartplotter
