One of the following indications occurs :
• Your radio plays the active transmission on the channel.
• If no activity is present, your radio is muted.

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 programmed 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 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 preven-
ted.
Quick-Key Override Your radio must be programmed to allow you
to use Quick-Key Override. This feature works
with either one of the two above variations. You
can override the transmit-inhibit state by quick-
keying the radio (press PTT button twice within
the programmed time limit).
