Digital PTT ID Support

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

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
Transmit Inhibit on Busy Channel with Carrier
Transmit Inhibit on Busy Channel with Wrong
Squelch Code
Quick-Key Override
104
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).
