A Selective Call is a call from an individual radio to another 
individual radio. It is a Private Call on an analog system.

When you receive a Selective Call: 

The LED blinks green.

Hold the radio vertically 1 to 2 inches (2.5 to 5.0 cm) from 
your mouth. Your radio unmutes and the incoming call 
sounds through the radio's speaker.

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 free for you to 
respond.

Press the PTT button to respond to the call. The LED lights 
up solid green.

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

Release the PTT button to listen.

If there is no voice activity for a predetermined period of 
time, the call ends.

You hear a short tone.

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

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

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.
