All Ships - Cobra MRF77 Manual

When a vessel is within range of a DSC Distress call, the radio receives the call,

will sound one (1) alert alarm. See pages 10-13 for descriptions of the different
alarms. Press any button to turn Off the alarm. The received call information continues
to display on the LCD.

2. Read and write down the distress information that
displays on the LCD (position data may or may not be
shown); then determine whether to answer the call.

Securite voice calls as well as sending Routine messages to all stations at once.
