Safety warnings
Warning: Safe operation
■Switch the radio off at petrol filling stations or
near flammable liquids or gases.
■Switch the radio off in the vicinity of explosive
devices and blasting zones.
■Using a handheld microphone or a radio while
driving a vehicle may violate the laws and legis-
lation that apply in your country or state. Please
check the vehicle regulations in your area.
Caution: EN 60950 requirements
This radio complies with the European Union standard
EN 60950 when operated up to the rated 33% duty cycle of
two minutes transmit and four minutes receive, and with
ambient temperatures of 30°C or lower.
Operation outside these limits may cause the external temper-
ature of the radio to rise higher than this standard permits.
Caution: High temperatures
The bottom surface of the radio and the heatsink fins can
become hot during prolonged operation. Do not touch these
parts of the radio.
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 condi-
tions 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.
■This device must only be used with authorized accessories
and antennas.

Safety warnings 9
English
■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 stand-
by 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.
Website: http://www.fcc.gov/oet/rfsafety/rf-faqs.html.
Important: Radio protection
Always remove the fuses from the radio power cable before
charging the vehicle battery, connecting a second battery or
using power from another vehicle (e.g. when
“jump-starting”the vehicle).

Tone type Meaning

14 Basic operation
English
Basic operation
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 15
English
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 conver-
sations 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.

16 Basic operation
English
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 intelli-
gibility are made audible.
Monitor
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.
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

Basic operation 17
English
amber LED flashes and, if the channel signalling is valid, the
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.
Voting
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.
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.
