7.3 USCG DSC WATCH
The USCG has plans to upgrade its VHF National Distress System (expected
by 2005), so at the time of printing only larger vessels that are required to
carry VHF DSC radios will be able to hear your distress transmission.
7.3.1 Maritime Mobile Service Identity (MMSI)
What is an MMSI?
An MMSI is a nine digit number used on Marine Transceivers capable of
using Digital Selective Calling (DSC). This number is used like a telephone
number to selectively call other vessels.
NOTE
THIS NUMBER MUST BE PROGRAMMED INTO THE RADIO TO OP-
ERATE THE QUEST+ DSC FUCTIONS.
How can I obtain an MMSI assignment?
Boat US offers free MMSI numbers. Visit the following to register:

7.3.2 Programming the MMSI
NOTE
User MMSI can be input only twice. If the user tries to input MMSI more
than twice, the radio will show the display on the right.
If the user needs to change the MMSI more than twice,
the transceiver will have to be sent to Factory Service.
Refer to the section 10.2 FACTORY SERVICE.
