Push-To-Talk (PTT) Button
The PTT button on the side of the radio has
two main functions:
- Press and hold down PTT button to initiate
and call and talk. Release the PTT button
to listen. The microphone is activated when
the PTT button is pressed.
- If a call is in progress, the PTT button allows
the radio to transmit to the other radios
that are part of the call.
Note: If the Talk Permit Tone 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 RCA Communications Systems 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.
Switching Between Analog and Digital
Mode
Each channel in your radio can be programmed
as an analog channel or a digital channel. Use
the Channel Selector Knob to switch between
an analog or a digital channel.
