Push-To-Talk (PTT) Button
The PTT button on the side of
the microphone serves two
basic purposes:
While a call is in progress,
the PTT button allows the
radio to transmit to other
radios in the call.
Press and hold down PTT
button to talk. Release the
PTT button to listen.
The microphone is activated when the PTT button is pressed.
While a call is not in progress, the PTT button is used to make
a new call (see Making a Radio Call on page 20).
If the Talk Permit Tone (see Turning the Talk Permit Tone On
or Off on page 69) or the PTT Sidetone is enabled, wait
until the short alert tone ends before talking.
During a call, if the Channel Free Indication feature is
enabled on your radio (programmed by your dealer), you
hear a short alert tone the moment the target radio (the
radio that is receiving your call) releases the PTT button,
indicating the channel is free for you to respond.
You also hear the Channel Free Indication tone if your call
is interrupted, for example when the radio receives an
Emergency Call.
You can turn off the Channel Free Indication tone or the
PTT Sidetone by disabling all radio tones and alerts
(see Turning the Radio Tones/Alerts On or Off on
page 68).

The Volume/Channel Knob can be programmed as dual
purpose for both volume and channel or as a volume-only
control.
To adjust volume, see Adjusting the Volume on page 2.
To change channels, push and hold the knob until channel
selection screen is displayed, then turn the knob to the required
channel.
To exit channel selection state, do any of the following.
