This feature allows you to see the radio ID (number) of the radio from whom you are currently receiving
a transmission. This ID, consisting up to a maximum of eight characters, can be viewed by both the
receiving radio and the dispatcher.
The ID number of your radio is also automatically sent every time the PTT button is pressed. This is a
per-channel feature. For digital voice transmissions, the ID of your radio is sent continuously during the
voice message.

message.
User can physically control the transmission of the radio especially during operation in hazardous
environments with this feature. An environment is considered hazardous when the power emitted by
the radio power amplifier could initiate an explosion or other dangerous reactions.
When the Transmit Inhibit feature is disabled, the radio functions according to its normal operations.
The radio sounds alert tone when user enters or exits this feature and also when PTT is pressed.
NOTICE: Acknowledgment of any messages required from the radio is not transmitted if the
Transmit Inhibition is enabled.

Description
You cannot transmit if traffic is detected on the
channel.
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).
