Using the Digital PTT ID Feature
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.
Your radio’s ID number is also automatically sent every time the 
PTT button is pressed. This is a per-channel feature. For digital 
voice transmissions, your radio’s ID is sent continuously during 
the voice message.
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:
Mode Description
Transmit Inhibit 
on Busy Channel 
with Carrier
You cannot transmit if any 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 prevented.
Quick-Key 
Override
This feature can work in conjunction 
with 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.
