two basic purposes:
• While a call is in

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 15).
Depending on programming, if the Talk Permit Tone or the PTT
Sidetone is enabled, wait until the short alert tone ends
before talking.
