your mouth. Your radio unmutes and the incoming call

short alert tone the moment the transmitting radio releases
the PTT button, indicating the channel is free for you to
respond.

Wait for the Talk Permit Tone to finish (if enabled) and speak
clearly into the microphone.

time, the call ends.

See Making a Selective Call on page 19 for details on making
a Selective Call.

Receiving an All Call

An All Call is a call from an individual radio to every radio on the
channel. It is used to make important announcements requiring
the user’s full attention.

Procedure:
When you receive an All Call:

1

A tone sounds and the LED blinks green. Your radio
unmutes and the incoming call sounds through the radio's
speaker.

2

If there is no voice activity for a predetermined period of
time, the All Call ends. An All Call does not wait for a
predetermined period of time before ending.

If the Channel Free Indication feature is enabled, you

hear a short alert tone the moment the transmitting radio
releases the PTT button, indicating the channel is now
available for use.

You cannot respond to an All Call.
NOTE: The radio stops receiving the All Call if you switch to a

different channel while receiving the call.
During an All Call, you are not able to use any
programmed button functions until the call ends.
