i

Personal death, serious injury or an explo­sion may occur.

Personal injury, fire hazard or electric
shock may occur.

Equipment damage may occur.

If disregarded, inconvenience only. No risk
of personal injury, fi re or electric shock.

i. The use of the citizen band radio service is licenced in

Australia by the ACMA Radiocommunications (Citizens
Band Radio Stations). Class Licence and in New Zealand
by the Ministry of Economic Development (MED) General
User Radio Licence for Citizen Band Radio and operation
is subject to conditions contained within these licences.

ii. Always listen on a channel (or observe channel busy indi-

cator) to ensure it is not already being used before trans­mitting.

iii. In Australia, channel 11 is the customary calling channel

for establishing communication. Channel 40 is the custom­ary road vehicle channel.

iv.

In Australia, except in an emergency, a CB transmitter shall
not be operated on UHF emergency channels 5 and 35.

v. No voice transmissions are permitted on data channels 22

and 23 (voice operation is inhibited on these channels).

vi. The user of this UHF CB communications device shall not

transmit selcall tones for longer than 3 seconds during any
60 second period.

OPERATIONAL NOTES

PRECAUTIONS

vii. UHF CB repeaters provide greater range through a base

station that re-transmits signals. Repeaters operate util­ising two channels (repeater input/repeater output). It is
important to avoid operation on locally used repeater in­put channels (which will be in the channel range 31 to 38
and 71 to 78, when they are authorised) or locally used
repeater receiving channels (in the channel range 1 to 8
and 41 to 48, when they are authorised), unless long dis­tance communication via the repeater facility is specifi cally
required. See the section on repeater operation for more
information.

iix. Please be aware that the UHF CB network may experi-

ence possible operational issues during the changeover to
narrowband. This transceiver operates on 12.5 kHz chan­nel spacing. During the changeover period from 25 kHz to

12.5 kHz spacing, there may be some loss of quality when

12.5 kHz (narrowband, 2.5 kHz deviation) transmissions
are received on 25 kHz (wide band, 5.0 kHz deviation)
equipment, and vice-versa. There may also be interfer­ence due to older equipment being operated on channels
adjacent to new narrowband channels, as the channel set­ting on these may cause some ‘overlap’. A list of currently
authorised channels can be found on the ACMA website
(Australia) and on the MED website in New Zealand.

R WARNING! NEVER connect the transceiver to an

AC outlet. This may pose a fi re hazard or result in an electric
shock.

NEVER connect the transceiver to a power source of more

than 27.6 V DC. This will damage the transceiver.

NEVER connect the transceiver to a power source using

reverse polarity. This will damage the transceiver.

NEVER cut the DC power cable between the DC plug and

fuse holder. If an incorrect connection is made after cutting,
the transceiver may be damaged.

NEVER expose the transceiver and microphone to rain,

snow or any liquids. The transceiver and microphone may
be damaged.

NEVER operate or touch the transceiver and microphone

with wet hands. This may result in an electric shock or dam­age the transceiver and microphone.

NEVER place the transceiver where normal operation of the

vehicle may be hindered or where it could cause bodily injury.

DO NOT push the PTT when not actually desiring to transmit.
DO NOT allow children to play with any radio equipment

containing a transmitter.

ii

PRECAUTIONS

(Continued)

DO NOT operate the transceiver near unshielded electri-

cal blasting caps or in an explosive atmosphere.

DO NOT operate the transceiver for extended periods

without running the vehicle’s engine. The transceiver’s power
consumption may soon exhaust the vehicles battery.

DO NOT set the transceiver in a place without adequate

ventilation. Heat dissipation may be affected, and the trans­ceiver may be damaged.

DO NOT use the chemical agents such as benzine or al-

cohol when cleaning, as they can damage the transceiver’s
surfaces.

USE Icom microphones only (supplied or optional). Other

manufacturer’s microphones have different pin assignments
and may damage the transceiver if attached.

DO NOT modify the transceiver. The transceiver warranty

does not cover any problems caused by unauthorized modi­fi cation.

DO NOT use harsh solvents such as benzine or alcohol

when cleaning, as they will damage the transceiver surfaces.

DO NOT use or place the transceiver in direct sunlight

or in areas with temperatures below –10°C or above +60°C.
The basic operations, transmission and reception of the
transceiver are guaranteed within the specifi ed operating
temperature range. However, the LCD display may not be
operate correctly, or show an indication in the case of long
hours of operation, or after being placed in extremely cold
areas.

BE CAREFUL! The transceiver will become hot when

operating it continuously for long periods of time.

MAKE SURE to turn OFF the transceiver power before

connecting the supplied/optional equipment.

This device complies with Standard Australia

Specifi cation No. AS/NZS 4365-2011.

REPEATER OPERATION

5

Repeater operation ■

Repeaters extend the operational range of the transceiver by
re-transmitting received signals. They are usually located on
the top of hills or mountains, as the elevation increases their
effectiveness, allowing the user to transmit and receive over
greater distances. During standard operation, or simplex,
transceivers transmit and receive on the same frequency.
When operating in the Duplex mode (i.e. accessing a re­peater), the transceiver will transmit and receive on different
frequencies. It will automatically do this when one of the re­peater channels is selected.

Accessing Repeater D

A repeater amplifi es received signals and re-transmits them
on a different frequency, allowing you to communicate over
greater distances with improved reliability. When using a re­peater, the repeater output channel (

‘RPT-41’ to ‘RPT-48’) must be selected.

You can search the accessible repeater in your local area
using the Repeater search scan function. (p. 32)

In addition to the tone squelch operation for silent stand-by,
the SelCall (Selective Calling) operation can be used. In tone
squelch (Group mode), there are 51 tone/code options when
making a call. SelCall offers a much more versatile 100,000
options when using 5-tone.
Other options in SelCall are the ability to call another unit
or Group operating on the same channel, as well as station
code/name information, status messages, answer back func­tionality and auto scan start. These, and many more, can be
set up via the optional CS-440N

NOTE:

• Channels 5 and 35 are used for the emergency chan­nels, and SelCall operation is not available on these
channels.

• SelCall transmission is restricted for total of 3 seconds in
a minute. If you try to transmit for more than 3 seconds,
