Maritime Mobile Service Identity (MMSI)
•
An MMSI is a nine (9) digit number used on a marine radio capable of using digital
selective calling (DSC). It is used to selectively call other vessels or shore stations
and is similar to a telephone number.
For your CobraMarine radio to operate in the DSC mode, you must enter your
Maritime Mobile Service Identity (MMSI) number. See page 62 for instructions
on how to enter your number.
