4 DSC FUNCTIONS
4.1 General
The RS86/RS87 features full Class D DSC (Digital Selective
Calling) functionality, enabling the user to make digitally se-
lected calls which are quicker and simpler to make than traditio-
nal voice calls using Ch16. Should a distress situation occur, a
Distress Alert call indicating the vessel’s identity and position
can be initiated and automatically establish distress communica-
tion on the emergency voice channel (normally Ch16).
Note DSC functions will only be available, if the MMSI number has
been entered into the radio (see section 3.2.1).
