converse normally on the channel. To use the
QUIET mode, refer to the QUIET Mode section
further below.
NOTE:
The QUIET mode overrides the normal
Squelch system to ensure that the radio remains
quiet even when the channel is busy. When
QUIET
is set, you may see the ‘BUSY’ icon
appear on the display indicating the channel is
being used. However, unless someone transmits
your SelCall Ident, nothing will be heard in the
speaker.
You can activate the QUIET mode on individual
channels ie. some channels can be set to remain
Quiet while others can remain open to all
incoming signals.
TIP:
Setting the QUIET mode is not mandatory.
You can still use SelCall on any channel whether
the QUIET mode is set or not.

can be viewed by briefly pressing the
CALL
