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 green LED blinks. 
2
The first line of the display shows the caller alias, and the 
RSSI icon. The second line displays All Call and the All 
Call icon.
3
Once 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
A programmed One Touch Access button 
Manual Dial (via Contacts) 
– 
This method is for Private Calls 
only and is dialed using a keypad microphone (see Making a 
Private Call by Manual Dial
 on page 66
NOTE: Your radio must have the Privacy feature enabled on 
the channel to send a privacy-enabled transmission. 
Only target radios with the same Privacy Key as your 
radio will be able to unscramble the transmission.
See Privacy on page 50 for more information.
