Receiving an All Ships Call
When an All Ships Call is received, the radio sounds an alert tone and
displays the type of call, the name or MMSI number (if the caller’s MMSI
number has not been programmed into your Phonebook) of the caller and the
time the All Ships Call was initiated. You are prompted to accept or decline
the call. For Urgency Calls, the prompt appears only if you have disabled
automatic channel changing (see page 82).
