Chapter 5: Digital Selective Calling (DSC)

5.5 Distress Calls

For a Distress Call transmission, the Ray54 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). When you make a Designated Distress Call, you can select from the following types:

UNDESIG (Undesignated)

FIRE

FLOODING

COLLISION

GROUNDING

LISTING

SINKING

ADRIFT

ABANDONING (Abandoning Ship)

PIRACY

MANOVERBD (Man Overboard)
