Operation
12
• A new channel is selected
For private channels, the feature will remain until manually removed.
Scrambler
On channels where it is allowed, you can set up voice scrambling, using
configuration mode (see SCRM on page 22).
Please note that if the radio is operating with scrambling on a channel, it
is impossible to communicate with other radios that are not programmed
with the same scrambler code. For this reason, be very careful
not to use
scrambled channels in emergency situations. Scrambled channels will
have a clear identification in the service field, e.g. "SCRM 3", while
selected. Not all regions allow the use of voice scrambling.
For maritime channels scrambling is automatically disabled when
• Product is turned off
• A new channel is selected
For private channels, scrambling will remain until manually removed.
Narrow band operation
The radio is prepared for narrow band operation. (see BAND on page 22).
Narrow band configuration is indicated with an “n” next to the channel
designator.
Note Prior to any initiation of scrambling, the operator must always
identify the calling station in clear voice (unscrambled) on that
channel. Use of scrambling may also be restricted by national
laws.
