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 al-
lows the radio to transmit to other radios in the
call.
Press and hold down
PTT
button to talk. Re-
lease the
PTT
button to listen.
The microphone is activated when the
PTT
but-
ton 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 32).
If the Talk Permit Tone (see
Turning the Talk Per-
mit Tone On or Off
on page 77) or the PTT Sid-
etone 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 will hear a short alert tone
the moment the target radio (the radio that is
receiving your call) releases the
PTT
button, in-
dicating the channel is free for you to respond.
You will 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 76).
