3.5.26.7 Receiving an All Ships Call
When receiving an All Ships Call, the unit's manner of response depends
on the type of call received.
When an URGENCY call is received, the DSC Distress alert is sounded.
The LCD displays a message that an URGENCY call is being received,
along with the sender's MMSI number, and a prompt to press ENT to
accept or CLR to log the call. The DSC Distress alert and the displayed
message continue until either ENT or CLR is pressed. If ENT is pressed,
the radio switches to Channel 16 in 25W mode and the contents of the
communication are stored in EEPROM. If CLR is pressed, the radio reverts
to the mode before receiving the URGENCY Call and the contents are
stored in memory.
