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 vessel. 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.

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 manoverboard 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 manoverboard 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).
