Push-To-Talk (PTT) Button The PTT button on the side of the radio has two
main functions:

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.

short or long press of the relevant programmable buttons. Or
