Adding a DSC Contact
You can make calls to a DSC contact from the chartplotter. See
page 62 for information on making an individual routine call.
1. While viewing a chart, press MENU > Other Vessels > dSC > dSC List
> add Contact.
2. Use the Rocker to enter the Maritime Mobile Service Identity (MMSI)
number of the vessel, and press SELECT.
3. Use the on-screen keyboard to enter the name of the vessel, and select
done.
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 first call in the call list.
From a chart screen, press MENU > Other Vessels > dSC > 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 the DSC distress call
was sent.
When you receive a DSC distress call:
1. Select Review to view details about the call.
2. Complete one of the following:
• Select Call with Radio to set up an individual routine call with
the radio to call the vessel in distress ( page 62 ). This option is only
available if you are using a Garmin NMEA 2000-compatible VHF
radio.
• Select Edit to 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. Select
Clear Report to delete the call report. Select Create waypoint to set a
waypoint at 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 turn to the man-overboard point.
If you cancel the man-overboard distress call on the radio, the man overboard
screen no longer appears.
