1.21 DSC Message Information

The DSC (Digital Selective Calling) message information feature provides, on the

chart plotter and radar displays, the MMSI no. and position* of the ships that have

transmitted a DSC message to you. A hexagon-shaped marker marks a ship’s posi-

tion. The marker is color-coded according to the type of DSC message sent, red for

distress and green for non-distress.

* Position at the time of message transmission. Position information is not updated.

This feature requires connection of a DSC capable radiotelephone that outputs the

DSC sentence in NMEA 0183 format.

1.21.1 DSC notification

When a DSC message (other than a distress message), such as position of the ship

is received, the message "DSC Position Report Received" appears in yellow on the

status bar at the top of the screen (see paragraph 2.10.7).

When a DSC message for distress is received, the message "DSC Distress Call Re-

ceived" appears in red on the status bar at the top of the screen. To delete the distress

message, tap the status bar.

1.21.2 How to show or hide the DSC message information

On the chart plotter or radar display, select [Targets] from the RotoKey menu then se-

lect [AIS/DSC]. The DSC information appears. To hide the DSC information, deselect

able in the [Full] mode (see section 14.1).

When you receive a DSC message, the appropriate DSC marker and the MMSI no. of

the transmitting ship appear on the chart plotter and radar displays.
