■ Channel naming

The IC-M72 has a capability to assign up to 10-character
channel names or comments for each operating channel, in-
cluding each weather channel. This provides easy recognition
of channel usage, or station names, etc.
When shipped from the factory, the IC-M72 is programmed
with default names for each VHF marine channel. These de-
faults can be changed, if desired.
You may replace the factory-set opening comment with a
comment of your own. The opening comment appears each
time the IC-M72 is powered ON. The comment may be up to
16 characters long.
