IMPORTANT
READ ALL INSTRUCTIONS carefully and com-
pletely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL — This
instruction manual contains important operating instructions
for the IC-440 UHF CB TRANSCEIVER.
EXPLICIT DEFINITIONS
OPERATING NOTES
BUSY CHANNEL
Always listen to a channel (or observe the channel busy indicator on the
display) to ensure that the channel is not already in use before transmitting.
CALLING CHANNELS (CB-11,CB-40)
In Australia channel 11 is the customary calling channel for establishing
communication and channel 40 is the customary road vehicle channel.
EMERGENCY CHANNELS (CB-05, CB-R5, CB-35)
In Australia except in an emergency, a CB transmitter must not be oper-
ated on UHF emergency channels 5 & 35.
NOTE: if the Radio is switched off while on an Emergency channel,
the Radio when switched on again, will be on the (software preset
channel) CB-11.
DATA CHANNELS (CB-22, CB-23)
No voice transmissions are permitted on data channels 22 and 23. (Note:
Voice operation is inhibited on channels 22 and 23).
REPEATER CHANNELS (CB-R1 to CB-R8)
UHF CB repeaters provide greater range through a base station that re-
transmits the signal. Repeaters operate utilizing two channels (repeater
input/ repeater output channels). It is important to avoid operation on
locally used repeater input channels (which will be in the range channels
31 to 38) or locally used repeater receiving channels (which will be in
the range channels 1 to 8), unless long distance communication via the
repeater facility is specifically required. (Please also see: Repeater Op-
eration, Repeater Search Scan).

WORD DEFINITION
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.

ii
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric shock.
RWARNING! NEVER operate the transceiver while
driving a vehicle. Safe driving requires your full attention—
anything less may result in an accident.
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.
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 use or place the transceiver in direct sunlight or
in areas with temperatures below –10°C or above +60°C.
DO NOT set the transceiver in a place without adequate
ventilation. Heat dissipation may be affected, and the trans-
ceiver may be damaged.
DO NOT use the chemical agents such as benzine or alcohol
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.

DAntenna installation
• Antenna location
To obtain maximum performance from the transceiver, se-
lect a high-quality antenna and mount it in a good location.
A non-radial antenna should be used when using a mag-
netic mount.
• Antenna connector
The antenna uses a PL-259 connector.
• PL-259 CONNECTOR
NOTE: There are many publications convering proper an-
tennas and their installation. Check with your local dealer
for more information and recommendations.

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