A Maritime Mobile Service Identity (MMSI) number is required to operate the DSC
equipment in this radio. This number directs DSC calls directly to your radio, much
like a telephone number. You can program the MMSI number yourself one time
only using the operation described in "My MMSI ID" on page 82. Otherwise, your
Raymarine dealer can program or change the number for you.
Full details on DSC call operation are described in Chapter 5.
