Using the Smart PTT Feature (Conventional Only)
Smart PTT is a per-personality, programmable feature used in
conventional radio systems 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.
If you try to transmit on an active smart-PTT channel, you hear
an alert tone, and the transmission is inhibited. The LED lights
up solid yellow to indicate that the channel is busy.
Three variations of smart PTT are available:
Accessing General Radio Information
Your radio contains information on the following:
• Radio Information
• IP Display
• Control Assignments
Note: If the feature inactivity timer is enabled, your radio
automatically exits the feature when your radio is left
idle long enough for the time to expire. You will hear
the Menu Inactive Exit Tone upon feature exit.
Accessing Radio Information
This feature displays the following information of your radio:
Mode Description

Code
You cannot transmit on an active channel
with a squelch code or (if secure-

the transmission is not prevented.

either of the two above variations. You
can override the transmit-inhibit state by
quick-keying the radio. In other words, two
PTT button presses within the
preprogrammed time limit.
