Viewing the 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 rst call in the Call List. To view the DSC
List, from a chart screen, select Menu > Other Vessels > DSC List.
Receiving Distress Calls
If your Garmin chartplotter and VHF radio are connected via 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.
The symbol designates a distress call in the DSC List and marks the position of a vessel on the
Navigation Chart at the time a DSC distress call is sent.
When you receive a DSC distress call:
1. Select Review to view details about the call.
2. Select from one of the following options:
Call with Radio—although the radio will automatically switch to monitor Channel 16 when
it receives a distress call, you can use this option to set up an individual routine call with the
radio to call the vessel in distress (page 52). This option is only available if you are using a
Garmin NMEA 2000-compatible VHF radio.
Edit—edit the vessel name and add a comment. If your radio is tracking the position of the
vessel, select Trail to show or hide the trail line for the vessel, and select Trail Line to change
the line color.
Clear Report—delete the call report.
Navigate To—Go To or Route To the position sent with the distress call (page 21).
The symbol marks the position of the vessel on the Navigation Chart at the time a DSC
distress call is sent.
Create Waypoint—set a waypoint at the position sent with the distress call.
Next Page/Previous Page—toggle between details related to the distress call and a
Navigation Chart marking the position sent with the distress call.
Man-Overboard Distress Calls Initiated from a VHF Radio
When your Garmin 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 displays
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 is no longer displayed.
Man-Overboard Distress Calls Initiated from the Chartplotter
When your Garmin chartplotter is connected to a Garmin NMEA 2000-compatible radio and you
activate navigation to a man-overboard location, the radio displays the Distress Call page to initiate
a man-overboard distress call. On the radio, press and hold the DISTRESS key for at least three
seconds to send the distress call.
For information on placing distress calls from your radio, see your Garmin VHF Radio Owner’s
Manual. For information on activating navigation to a man-overboard location, see page 23.
