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 green LED blinks.

2The first line of the display shows the caller alias, and the RSSI icon. The second line displays All Call and the All Call icon.

3Once the All Call ends, the radio returns to the previous screen before receiving the call.

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 18 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 continue with any menu navigation or editing until the call ends.

Making a Radio Call

You can select a channel, subscriber alias or ID, or group alias or ID by using:

•The Channel Rocker
