Smart PTT (Conventional Only)
Smart PTT is a per-personality, programmable feature used to keep radio users from talking over other
radio conversations. When Smart PTT is enabled in your radio, you cannot transmit on an active
channel.
The following table shows the variations of Smart PTT.
Mode Description
Transmit Inhibit on Busy Channel with Carrier You cannot transmit if traffic is detected on the
channel.
Transmit Inhibit on Busy Channel with Wrong
Squelch Code
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.
Quick-Key Override 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).
6.19.12
Transmit Inhibit
This feature allows you to stops all transmission including voice and data. The radio can receive
messages but not able to reply the acknowledgment request of the received message.
This feature is available for APCO 25 trunking, Type II trunking and Conventional operations for all
APX radios.
You can physically control the transmission of the radio especially during operation in hazardous
environments. An environment is considered hazardous if radio transmission could initiate an explosion
or other dangerous reactions.
6.19.12.1
Enabling Transmit Inhibition
Procedure:
1 Press the Transmit Inhibit programmable button.
NOTICE: If the user has disabled TX Inhibit using the menu and then moves the switch
to the position where TX Inhibit is enabled, the new value overwrites the menu value.
The display shows Tx inhibit on. You hear a sequence of short, low-high tones to indicate
that transmission is inhibited.
Pressing PTT triggers the radio sounds a constant short, low-pitched tone (reject tone).
NOTICE: The status of the Transmit Inhibit does not change after the radio powers up.
