12 Basic Operation

Transmit Timer

Your radio may have a transmit timer that limits the

amount of time you can transmit continuously. When the

transmit timer is about to expire, the red LED flashes and

the radio gives three beeps. You must release the PTT

before you can transmit again.

Note: Your radio may be unable to transmit for

a short time after the transmit timer has

expired.

Receiving a

Call

When there is valid activity on your radio’s currently

selected channel or group, the radio then unmutes and

you can hear the call.

If the incoming call contains special signalling that

matches the signalling programmed for your radio, the

green LED flashes and your radio may give a ringing tone.

What You

Hear on a

Channel

Your radio may be programmed so that you hear all

conversations on a channel, or your user group may be

segregated from other user groups by using special

signalling. The special signalling is used to control the

muting and unmuting of your radio, so that your radio is

muted when other user groups are talking and unmuted

for members of your user group.

There are two muting controls that operate in your radio:

■ signalling mute, and

■ squelch.

Signalling Mute

The radio’s signalling mute only allows the radio to

unmute if the incoming call carries the tones specific to

your user group. Your user group may use tones that are

either audible, subaudible or both.
