UHF TRANSCEIVER

i
IMPORTANT
READ ALL INSTRUCTIONS carefully before using
the IC-440N 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 channel busy indi-
cator) to ensure it is not already being used before trans-
mitting.
iii. In Australia, channel 11 is the customary calling channel
for establishing communication. Channel 40 is the custom-
ary 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.

ed (Japan) in Japan, the United States, the United Kingdom, Germany, France,

PRECAUTIONS
RWARNING! NEVER connect the transceiver to an
AC outlet. This may pose a fire 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 dam-
age 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.
OPERATIONAL NOTES
vii.UHF CB repeaters provide greater range through a base
station that re-transmits signals. Repeaters operate util-
ising two channels (repeater input/repeater output). It is
important to avoid operation on locally used repeater in-
put 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 dis-
tance communication via the repeater facility is specifically
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 chan-
nel 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 interfer-
ence due to older equipment being operated on channels
adjacent to new narrowband channels, as the channel set-
ting 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 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 trans-
ceiver 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 modi-
fication.
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 specified 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
Specification No. AS/NZS 4365-2011.

ANTENNA INFORMATION
For radio communications, the antenna is of critical impor-
tance, to maximize your output power and receiver sensitiv-
ity. The transceiver accepts a 50 antenna 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.

Hold downqfor 2 seconds to turn ON the power.
If the transceiver is programmed with a start-up password,w
this needs to be entered before the transceiver can be op-
erated.
• The keys in the table below can be used for password input:
• The transceiver detects numbers in the same block, as identical.
Therefore “01234” and “56789” are the same.
