Chapter 5: Digital Selective Calling (DSC) 63
5.2 Distress Calls
For a Distress Call transmission, the Ray49E takes the position and time
information from the input NMEA data along with your MMSI and converts it into
a digital “packet”. When transmitted, this digital information lets other ships and
shore stations equipped with appropriate DSC equipment know where you are
and that you are in a Distress situation.
Your call can specify the nature of the Distress (designated call) or not
(undesignated call).
Sending a Distress Call
Lift the spring-loaded door on the front panel of the transceiver.
Undesignated (Quick) Distress Call
To send a distress call without specifying its nature:
• Press and hold the red
DISTRESS key for 3 seconds to initiate the call. During
this time, the radio beeps, the display flashes and a timer counts down
03...02...01.
