Receiving and Responding to a Selective Call
A Selective Call is a call from an individual radio to another
individual radio. It is a Private Call on an analog system.
Procedure:
When you receive a Selective Call:
1 The LED blinks green.
2 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.
3 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.
4 Press the PTT button to respond to the call. The LED lights
up solid green.
5 Wait for the Talk Permit Tone to finish (if enabled) and speak
clearly into the microphone.
6 Release the PTT button to listen.
7 If there is no voice activity for a predetermined period of
time, the call ends.
8 You hear a short tone.
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.
