DSC Call Function, Individual, Group, ALL Ships | Raymarine Ray54

32	Ray54 VHF Radio

5.1DSC Call Function

DSC Call Mode is used to initiate DSC Individual, Group, All Ships, Distress and Position Request calls and to access the DSC Call Logs and Phonebook.

The channel remains unchanged and you can perform normal TX operation. DSC mode is exited when transmitting.

Press and release the CALL/MENU key while in normal operation mode to enter DSC Call Mode.

Note: Distress calls are made using the DISTRESS key.

The Ray54’s DSC Call type and structure are as follows:

DSC Call Type	Description

INDIVIDUAL	Makes a ROUTINE DSC call to a specific station identified by its MMSI
	number.

GROUP	Sends transmissions that are only received by radios that share a common
	Group MMSI number. Up to 3 Group MMSI numbers can be stored and
	called.

ALL SHIPS	Sends out a message to all ships within range that you need assistance but
	the situation is not serious enough for a Distress Call. All Ships calls should
	only be used if hailing for assistance on channel 16 fails. There are two
	types of All Ships Calls: SAFETY for advisory alerts and URGENCY for assis-
	tance when life is not in immediate danger.

DISTRESS	Sends out the position and time information from the input NMEA data
	along with your MMSI number. 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.
