Warning: FCC RF exposure limits
This product generates RF (radio frequency) energy during
transmissions. This device must be restricted to work-related
use in an occupational/controlled exposure environment.
The radio operator must have control of the exposure conditions and duration of all persons exposed to the antenna of
this transmitter to satisfy FCC RF exposure compliance. This
device is not approved for general population use.
10 Safety warnings
■ This device must only be used with authorized accessories
and antennas.
■ The operator must ensure that the minimum safe distance
of 0.9m (35 inches) between persons and the antenna is
maintained during transmissions.
■ This minimum safe distance is based on the assumption
that there is a duty cycle of 50% transmit mode to standby or receive modes. The radio is in transmit mode when
the PTT (press-to-talk) key on the microphone is pressed
and the control head red LED (light emitting
diode) glows.
Please refer to the following website for more information on
what RF energy is and how to control your exposure to
assure compliance with established RF exposure limits.
Radio protection
Always remove the fuses from the radio power cable before

English
This section describes the basic operation of your radio,
including turning the radio on and off, adjusting volume,
selecting channels, making calls and receiving calls.
Turning the radio on and off
A long press of the on/off key turns the radio either on or
off. When the radio is first turned on, the red, green and
amber LEDs flash briefly and the radio gives two short beeps.
Adjusting the volume
Rotate the volume control clockwise to increase the speaker
volume and counterclockwise to decrease the volume. The
volume control also changes the volume level of the radio’s
audible indicators.
Selecting a channel
Use the channel selection keys or to scroll through
the channel list until the channel you want is displayed.
Making a call
1 Select the required channel using the channel selection
keys or .
2 Check the green LED.
If the green LED is glowing, the channel is busy and you
cannot transmit.
3 Once the channel is clear (the green LED is off), lift the
microphone off the microphone clip.
4 Hold the microphone about 5cm (2 inches) from your
mouth and press the PTT key to transmit.
5 Speak clearly into the microphone and release the PTT
key when you have finished talking.
Note: You cannot change channels while transmitting.
Basic operation
16 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.
English
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.
Basic operation 17
English
Monitor
Scanning
18 Basic operation
Squelch
The radio’s squelch allows the radio to unmute only when the
strength of the incoming signal is above a predetermined
threshold. This means that only signals of reasonable intelligibility are made audible.
The monitor function is used to check that the channel is
clear before you make a call. While monitor is on, the green
LED flashes continually.
Activating monitor
1 Press the monitor function key and monitor overrides the
signalling mute, allowing you to hear any traffic on
the channel.
Note: Your radio may be programmed to activate monitor
whenever the microphone is off the microphone clip.
2 Press the monitor function key again to turn monitor off,
and the green LED no longer flashes.
Activating squelch override
1 Press and hold the monitor function key for longer than
one second to override both squelch and the
signalling mute.
This allows you to hear even faint and noisy signals.
2 Press the monitor function key again to return the radio
to a quiet state.
Note: Squelch cannot be overridden when the radio
is scanning.
The scan function is used to monitor a programmed group of
channels, looking for activity. When activity is detected on a
scan group channel, the radio stops on that channel. The
amber LED flashes and, if the channel signalling is valid, the
Voting
radio unmutes and you can hear the call. Scanning resumes
when the channel is no longer busy or the signalling is no
longer valid.
One or two priority scan channels may be set. These channels
are scanned more often than other channels and are scanned
periodically when a non-priority channel is busy.
Activating scanning
1 Place the microphone on the microphone clip.
2 Press the function key assigned to scanning. The amber
LED glows to show that the radio is scanning.
3 Press the scanning function key again to cancel scanning,
and the amber LED no longer glows.
Nuisance delete
If a member channel of the scan group is busy for a long time
and you do not wish to hear the conversation, you can use
the function key assigned to nuisance delete to temporarily
delete it from the scan group.
Alternatively, press and hold the scanning function key.
When the scan group is next selected, the deleted channel is
again part of the scan group.
Note: Priority channels cannot be removed from the scan
group using the nuisance delete function.
A group of channels carrying the same traffic can be grouped
together in a voting group. When you press the function key
assigned to voting, the best communication channel is
always selected for you to use.
English
Nuisance delete
If you wish to delete one of the channels from the voting
group, you can use the function key assigned to nuisance
delete to temporarily delete it from the voting group.
Basic operation 19
Troubleshooting
When your radio won’t turn on
English
Removing the radio from the vehicle
If the red, green and amber LEDs on the control head do not
light up when the radio is turned on, it is likely that no power
is reaching the radio. Check the following:
■ Is the power connector firmly plugged into the rear of
the radio?
■ Are the in-line fuses in good condition?
■ Is the power cable securely connected to the vehicle bat-
tery or power supply?

Battery supply voltage
This radio is designed to operate from a nominal 12V negative
ground supply and may draw up to 8A of current (25W radios)
or 15A of current (40 W/50W radios). The radio will tolerate a
supply voltage range of 10.8V to 16.0V at the radio.
Caution: In vehicles with a supply voltage greater than
16.0V, such as many trucks, it is essential to
provide a suitably rated DC to DC converter. This
will isolate the radio from excessive battery voltage
and provide the correct DC operating conditions.
Connecting the power cable
Caution: Disconnecting the vehicle’s battery may cause
problems with electronic equipment, such as vehicle alarms, engine management systems and incar entertainment systems. Check that the vehicle
owner has the necessary information to make all
electronic equipment function correctly after
battery reconnection.
Caution: If the battery is not disconnected, exercise extreme
caution throughout the installation and install the
fuses only when the installation is ready to be
checked (see “Checking the installation” on
page 37).
1 Disconnect the vehicle’s battery, unless specifically
prohibited from doing so by the customer, vehicle manufacturer, agent or supplier.
2 Run the power cable between the radio’s mounting posi-
tion and the vehicle battery.
Caution:
The power cable should be protected from engine
heat, sharp edges and from being pinched or crushed.
3 Cut the power cable to length, allowing about 20cm
(8 inches) excess at the radio end.

4
Cut the negative and the positive wires where the in-line fuse
holders will be placed (as close to the battery as possible).
Caution: Do not install the fuses until the installation is
ready to be checked.
5 Insert each end of the negative wire into one of the in-
line fuse holders and crimp them to force the metal
contacts onto the wires.
6 Connect the negative wire to the battery ground.
7 Repeat step 5 for the positive wire and connect it to the
positive terminal of the battery.
Mounting the U-bracket
The U-bracket can be used to install the radio on the dashboard or on any sufficiently flat surface, using the self-drilling
screws and washers provided in the installation kit.
Caution: When mounting the radio, check whether the
mounting surface needs to be reinforced.
Caution: The U-bracket must be installed using at least
four screws.
1 If the U-bracket is being mounted over a curved surface,
bend the U-bracket tabs slightly, to match the
surface shape.
2 Drill any holes required for cables and install suitable
grommets or bushings in the holes.
Caution: Check that the U-bracket is not distorted when the
screws are tightened.
3 Screw the U-bracket in the
chosen mounting position using
the self-drilling screws and
washers provided.
Tip: For more precise
positioning, predrill

the self-drilling screws. Reduce the hole size in metal that
is less than 1mm (1/32 inch) thick.
English
Installing the radio in the U-bracket
1 Connect the antenna and power cables to the rear of
the radio.
2 Position the radio in the U-bracket so that the holes in the
U-bracket line up with the holes in the radio chassis.
3 Screw the radio into position using the four thumb screws
but without fully tightening the screws.
4 Position the radio in the U-bracket for best viewing angle,
then tighten the thumb screws.

Checking the installation
1 Insert the fuses into the power leads.
English
2 Switch on the radio to confirm that it is operational.
Caution: Do not transmit yet.
3 Connect an in-line power meter between the radio and
the antenna.
4 Transmit and measure the forward and reflected
power levels.
Less than 4% of the forward power should be reflected. If
this is not achieved, check the installation, including the
antenna length.
5 Radios with a user interface only:
Once the reflected power levels are within tolerance,
make a call to another party on the radio (see “Making a
call” on page 16).
Other installation options
Contact your radio provider for further information.
