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:

1A tone sounds and the LED blinks green.

2The Group Call icon appears in the top right corner. The first text line shows the caller alias. The second text line displays All Call. Your radio unmutes and the incoming call sounds through the radio’s speaker.

3Once the All Call ends, the radio returns to the previous screen it was on before receiving the call. An All Call does not wait for a predetermined period of time before ending. If the Channel Free Indication feature is enabled, you will 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.

See Making an All Call on page 28 for details on making 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 will not be able to use any programmed button functions until the call ends.
