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.
GENERAL INFORMATION
i. The Citizen Band Radio Service is licensed in Australia by
the ACMA Radiocommunications (Citizens Band Radio
Stations) Class Licence and in New Zealand the Ministry
of Economic Development New Zealand (MED). Opera-
tion is subject to conditions contained in the General User
Radio Licence for Citizens Band Radio.
ii. The transceiver must not be operated on channel 5 and
35, unless in an emergency. No voice transmissions are
permitted on channels 22 and 23, as these are used for
data (telemetry/telecommand). The transceiver will inhibit
transmission on channels 22 and 23.
iii. Always listen on a channel (or observe channel busy indi-
cator) to ensure it is not already being used before trans-
mitting.
iv. This transceiver operates on 12.5 kHz channel spacing.
During the changeover period from 25 kHz to 12.5 kHz,
there may be some loss of quality and/or audio level when
12.5 kHz (narrowband) transmissions are received on 25
kHz (wide band) equipment, and vice-versa. There may
also be interference caused by older equipment operat-
ing on channels adjacent to narrowband channels, as the
channel setting on these may cause some ‘overlap.’

porated (Japan) in Japan, the United States, the United Kingdom, Germany,
France, Spain, Russia and/or other countries.

PRECAUTIONS
CAUTION: MAKE SURE the flexible antenna, bat-
tery pack and jack cover are securely attached to the trans-
ceiver, and that the antenna and battery pack are dry before
attachment. Exposing the inside of the transceiver to dust or
water will result in serious damage to the transceiver.
DO NOT operate the transceiver near unshielded electri-
cal blasting caps or in an explosive atmosphere.
DO NOT push [PTT] when not actually intending to transmit.
DO NOT use or place the transceiver in direct sunlight or in
areas with temperatures below –30°C or above +60°C.
The basic operations, transmission and reception of the trans-
ceiver are guaranteed within the specified operating tempera-
ture 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.
DO NOT modify the transceiver. The transceiver warranty does
not cover any problems caused by unauthorized modification.
DO NOT use harsh solvents such as benzine or alcohol
when cleaning, as they will damage the transceiver surfaces.
BE CAREFUL! The transceiver will become hot when
operating it continuously for long periods of time.
RDANGER! NEVER short the terminals of the battery
pack.
RDANGER! Use and charge only specified Icom bat-
tery packs with Icom radios or Icom chargers. Only Icom bat-
tery packs are tested and approved for use with Icom radios
or charged with Icom chargers. Using third-party or coun-
terfeit battery packs or chargers may cause smoke, fire, or
cause the battery to burst.
RWARNING! NEVER hold the transceiver so that
the antenna is very close to, or touching exposed parts of
the body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
RWARNING! NEVER operate the transceiver while
driving a vehicle. Safe driving requires your full attention—
anything less may result in an accident.

iii
BE CAREFUL! The IC-41W meets IP67* requirements
for dust-tight and waterproof protection. However, once the
transceiver has been dropped, dust-tight and waterproof pro-
tection cannot be guaranteed because of possible damage to
the transceiver’s case or the waterproof seal.
* Only when the jack cover or the optional HM-168LWP is
attached.
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or batteries from
the transceiver when not using it for a long time. Otherwise,
the installed battery pack or batteries will become exhausted,
and will need to be recharged or replaced.
MAKE SURE to turn the transceiver power OFF before
connecting the supplied/optional equipment.
This device complies with Standard Aus-
tralia Specification No. AS/NZS 4365-2002
and AS/NZS 4295: 2004.
