RADIO CALLS

SELECTIVE CALL

Making a Selective Call

You can make a selective call to a particular
radio, known as an individual call, or to a selected
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 pro-
grammed 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 - 5cm from the
microphone. Release PTT to listen.
4.
When transmitting the red indicator will
light continuously.
Your radio may be conÞgured for ÔTransmit
InhibitÕ 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.

Receiving a Selective Call

When you receive a selective call, you will hear
either an individual call alert tone
, or a group call alert tone
and the LED Indicator will
light (yellow).
To answer the call:
1.
Press the PTT button or Call button.
2.
The call will terminate automatically when
the conversation has ended or press the
Monitor button.
