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 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.

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.
