Section 2: Basic Radio Operation
This section addresses the radio’s basic operations, which includes
MMSI (Maritime Mobile Service Identity) number setup. If you already
have your MMSI number programmed into the radio and have a strong
understanding of the radio's basic functions, move on to
Section 3:
Advanced Radio Operation.
We're going to kick off the operation section with a brief description of
the radio's basic functions. That will be followed by some important in-
formation on Digital Selective Calling and basic instructions on how to
make and receive calls.

, the up-and-
down arrow keys. When you press any of the keys a tone will sound. If
you push a key and a 3-beep tone sounds, there is an error or the func-
tion is not supported by the radio. You’ll notice several functions re-
quire you to hold down a key for a few seconds. In those cases, a single
beep sounds, then, after a few moments, a second beep will be heard to
let you know you have successfully changed the mode.
