5.5.4 Expanded MMSI registration
CAUTION
Always set the expanded MMSI in the bridge of the vessel to zero (0). If setting
to another value other than zero, DSC calls may not be received.
If there are multiple DSC devices having the same 9-digit MMSI on board a ship, setting the 10th
digit of the MMSI number to a non-zero value is available to distinguish them in the case of routine
individual calls.
The handling of 10-digit MMSI is as follows.
・ When sending a routine individual call, the caller ID (own ship station's MMSI) is 10-digit MMSI.
・ When receiving a routine individual call, the DSC having the identical address only treats the
message, i.e. mainly the DSC having "0" as the 10th digit of MMSI receives an individual call
addressed to the own station.
・ When sending an acknowledgement to a received individual call, the address of the call is
entered the caller's ID of the individual call as it is, i.e. if the 10th digit of the caller's ID is not "0",
the address is 10-digit MMSI automatically.
■ Procedure ■
When changing the 10th digit of the MMSI other than zero (0), touch the [EXP MMSI]
button to input the value.
