Description
You cannot transmit on an active channel with a
squelch code or (if secure-equipped) encryption
key other than your own. If the PL code is the
same as yours, the transmission is not prevent-
ed.
Your radio must be preprogrammed to allow
you to use Quick-Key Override. This feature
works with either one of the two above varia-
tions. You can override the transmit-inhibit state
by quick-keying the radio (press PTT button
twice within the preprogrammed time limit).
