Communication Procedures

Receiving Calls

When a call is received, the speaker will unmute (open)
and the red LED indicator (4) will flash (Channel Busy).
Unless you have some form of selective signalling on a
channel, you will hear all calls on the channel.
Private Line (CTCSS) Signalling
If you use this form of signalling on your receive
channels, your speaker will unmute only when it
receives a call accompanied by this form of
signalling. This greatly reduces interference heard
on a channel, reducing operator fatigue.
This form of reception can be disabled using the
monitor button (5).

Outgoing Calls

When you have selected a channel, you are ready
to transmit. You should only make a call when the
channel is free (red indicator (4) does not flash). If
in doubt, press the monitor button (5) to listen to the
channel.
Take the microphone out of its holder. Press the
transmit (PTT) key (11) on the side of the
microphone while talking, release it while listening.
Speak in a normal tone of voice, keeping a distance
of 5-10 cm from the microphone. When transmitting
the red indicator (4) will light continuously. Your
radio may be configured for 'Transmit Inhibit' under
certain conditions (e.g. when the channel is in use
by other users) in which case, the error tone will
sound when you press the PTT key to indicate that
transmission is inhibited.
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. The
radio may be programmed to inhibit retransmission
within a preset time.
Hang up the microphone in its holder when your
conversation has ended.
