Making a Selective Call
You can make a selective call, to a particular radio,
known as an individual call, or group of radios, known
as a group call.
To make a Selective Call:
1. Press the PTT or Call Button (depending on the
way your radio has been programmed by your
dealer) to set up the call.
2. Wait until the conversation has been set up,
which means you are authorised to use the
system.
3. Talk with your mouth 2.5 – 5 cm from the
microphone. Release PTT to listen.
4. The red indicator lights up when the radio is
transmitting.
Your radio may be configured for ‘Transmit Inhibit’
under certain conditions (e.g. when the channel is in
use by others) in which case, the channel busy tone
will sound when you press the PTT or call button to
indicate that transmission is inhibited.
When the channel is free, the Channel Free beep
will sound, and you can make a
call.
If your radio is equipped with a transmit time out
timer (TOT), a warning tone
will
sound a few seconds before the transmission is cut
off. Your radio may be programmed to inhibit
retransmission within a preset time.
