ACR / Nauticast™ Technical Information

Default MMSI Settings

We have received reports from some administrations who monitor Class A AIS messages that some of the ACR

/ Nauticast AIS systems transmit a default MMSI (1193046).

Causes

• User fails to enter an MMSI when system is installed.

• MMSI reverts to default value when external power is lost and

the internal memory backup battery becomes discharged.

Corrective Actions

• Users are reminded to check operation of their AIS to assure that

an MMSI has been correctly installed in the AIS.

• Users can check for condition of memory backup battery periodically as follows:

• With AIS powered up, check that proper MMSI is entered into the AIS system.

• Remove power from the AIS system for approximately 2 minutes.

• Apply power to the system and check that the correct MMSI is present.

• If step 3) shows default MMSI (1193046), the memory backup battery is probably discharged and must

be serviced.
