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.
•
Use the
SELECT/ENT
knob to select the
ALL SHIP’S
topic.
