Push-To-Talk (PTT) Button

The PTT button on the side of the radio ( ) 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 33).

If the Talk Permit Tone 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 a continuous talk prohibit tone, if

your call is interrupted, indicating that you should

release the PTT button, for example when the radio

receives an Emergency Call.

Programmable Buttons

Your dealer can program the programmable buttons

as shortcuts to radio functions depending on the

duration of a button press:
