Receiving a
Call
What You
Hear on a
Channel
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.
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.
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:
I signalling mute, and
I 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.
