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 18).
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
will 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 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 68).
Switching Between Conventional Analog
and Digital Mode
Each channel in your
radio can be
configured as a
conventional analog or
conventional digital
channel.
To switch between an analog or a digital channel, use the
• Scroll Up/Down buttons, or
• Volume/Channel Knob
When switching from digital to analog mode, certain features
are unavailable. Icons for the digital features (such as
Messages) reflect this change by appearing ‘grayed out’.
Disabled features are hidden in the menu.
