All Ships Call
The All Ship’s call allows you to send an Urgent or Safety DSC call to nearby
vessels without having to know their MMSID numbers. The All Ship’s call
may be used in situations that are serious but do not warrant a distress call,
and voice communication attempts have failed.
To send an All Ship’s call:
• Press the
CALL
key. The call menu appears in the display.
