have a clear identification in the service field, e.g. "CTCSS 22", while
selected. Not all channels are allowed for CTCSS use.
In maritime channel modes CTCSS is automatically disabled when
• Product is turned off
• A new channel is selected
For private channels and ALT channel mode, 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 25).
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.
In maritime channel modes scrambling is automatically disabled when
• Product is turned off
• A new channel is selected
For private channels and ALT channel mode, scrambling will remain until
manually removed.
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.
