IMPORTANT
READ ALL INSTRUCTIONS carefully before
using the IC-450 UHF TRANSCEIVER.
KEEP THIS INSTRUCTION MANUAL, as it
contains important operating information that may be useful
in the future.
EXPLICIT DEFINITIONS
WORD DEFINITION
RDANGER! Personal death, serious injury or an explo-
sion may occur.
RWARNING! Personal injury, fire hazard or electric
shock may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
OPERATIONAL NOTES
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 the channel busy
indicator) 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.

ii
PRECAUTIONS
RWARNING! NEVER connect the radio to an AC
outlet. This may pose a fire hazard or result in an electric shock.
CAUTION: NEVER operate or touch the radio and
microphone with wet hands. This may result in an electric
shock or damage the radio and microphone.
CAUTION: NEVER connect the radio to a power
source of more than 27.6 V DC. This will damage the radio.
CAUTION: NEVER connect the radio to a power
source using reverse polarity. This will damage the radio.
CAUTION: NEVER cut the DC power cable between
the DC plug and fuse holder. If an incorrect connection is
made after cutting, the radio may be damaged.
CAUTION: NEVER expose the radio and microphone
to rain, snow or any liquids. The radio and microphone may
be damaged.
CAUTION: NEVER place the radio where normal
operation of the vehicle may be hindered or where it could
cause bodily injury.
DO NOT push the PTT when not actually intending to transmit.
DO NOT allow children to play with any radio equipment
containing a transmitter.
OPERATIONAL NOTES
vii. UHF CB repeaters extend the operational range of
your radio. Repeaters operate utilising two channels
(repeater input/repeater output). It is important to avoid
operation on locally used repeater input channels (in the
channel range of 31 to 38 and 71 to 78) or locally used
repeater output channels (in the channel range of 1 to 8
and 41 to 48), unless long distance communication via
the repeater is specifically required. See the section on
repeater operation for more information.
viii. Please be aware that the UHF CB network may
experience 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.

iii
PRECAUTIONS (Continued)
DO NOT operate the radio near unshielded electrical
blasting caps or in an explosive atmosphere.
DO NOT operate the radio for extended periods
without running the vehicle’s engine. The radio’s power
consumption may soon exhaust the vehicles battery.
DO NOT set the radio in a place without adequate
ventilation. Heat dissipation may be affected, and the radio
may be damaged.
DO NOT use harsh solvents such as benzine or alcohol
to clean the radio, as they will damage the radio’s surfaces.
If the radio becomes dusty or dirty, wipe it clean with a soft,
dry cloth.
USE Icom microphones only (supplied or optional). Other
manufacturer’s microphones have different pin assignments
and may damage the radio if attached.
DO NOT modify the radio. The radio warranty does not
cover any problems caused by unauthorized modification.
DO NOT use or place the radio in direct sunlight or in
areas with temperatures below –10°C or above +60°C. The
basic operations, transmission and reception of the radio
are guaranteed within the specified operating temperature
range. However, the LCD display may not operate correctly,
or show an indication in the case of long hours of operation,
or after being placed in extremely hot or cold areas.
BE CAREFUL! The radio will become hot when
operating it continuously for long periods of time.
MAKE SURE to turn OFF the radio power before
connecting any supplied/optional equipment.
This device complies with Standard
Australia Specification No. AS/NZS 4365-
2011.

ANTENNA INFORMATION
For radio communications, the antenna is of critical
importance, to maximize your output power and receiver
sensitivity. The transceiver accepts a 50 Ωantenna and a
less than 1:1.5 Voltage Standing Wave Ratio (VSWR).
High SWR values not only may damage the transceiver,
but also lead to TVI or BCI problems.
