PRECAUTIONSRECOMMENDATION

CLEAN THE TRANSCEIVER THOROUGHLY IN A BOWL
OF FRESH WATER after exposure to saltwater, and dry

it before operating. Otherwise, the transceiver’s keys,
switches, and controllers may become unusable, due to salt

crystallization, and/or the charging terminals of the battery

pack may corrode.

NOTE: If the transceiver’s waterproof protection appears
defective, carefully clean the transceiver with a soft,
damp (fresh water) cloth, then dry it before operating.
The transceiver may lose its waterproof protection if the
case, jack cap, or connector cover is cracked or broken,
or the transceiver has been dropped. Contact your Icom
distributor or your dealer for advice.

R DANGER! NEVER short the terminals of the battery
pack. Shorting may occur if the terminals touch metal
objects such as a key, so be careful when placing the
battery packs (or the transceiver) in bags, and so on. Carry
them so that shorting cannot occur with metal objects.
Shorting may damage not only the battery pack, but also the
transceiver.
R DANGER! NEVER use or charge Icom battery packs
with non-Icom transceivers or non-Icom chargers. Only Icom
battery packs are tested and approved for use with Icom
transceivers or charged with Icom chargers. Using third­party or counterfeit battery packs or chargers may cause

smoke, re, or cause the battery to burst.

R DANGER! NEVER operate the transceiver near
unshielded electrical blasting caps or in an explosive
atmosphere.
R WARNING! 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 (2 to 4 inches) away from the lips and the transceiver is
vertical.
R WARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
The continuous high volume operation may cause a ringing
in your ears. If you experience the ringing, reduce the
volume level or discontinue use.

ii

PRECAUTIONS (Continued)

CAUTION: DO NOT use harsh solvents such as Benzine or

alcohol when cleaning. This could damage the equipment
surfaces. If the surface becomes dusty or dirty, wipe it clean
with a soft, dry cloth.
CAUTION: DO NOT place or leave the transceiver in
excessively dusty environments. This could damage the
transceiver.
CAUTION: DO NOT expose the transceiver to rain, snow
or any liquids. The transceiver meets IP67 requirements
for dust-protection and splash resistance. However, once
the transceiver has been dropped, dust protection and
splash resistance cannot be guaranteed due to the fact
that the transceiver may be cracked, or the waterproof seal
damaged, and so on.
DO NOT place or leave the transceiver in direct sunlight or

in areas outside of the specied temperature range:
Operating temperature range: –30°C (–22˚F) ~ +60°C (+140˚F)

Keep the transceiver in a secure place to prevent use by

unauthorized persons.

BE CAREFUL! Even if the volume level is set low, the
beeps of the Man Down, Lone Worker and MOB functions
are very loud.

Icom is not responsible for the destruction, damage to, or
performance of any Icom or non-Icom equipment, if the

malfunction is because of:

• Force majeure, including, but not limited to, res,
earthquakes, storms, oods, lightning, other natural

disasters, disturbances, riots, war, or radioactive
contamination.

BATTERY CHARGING

■ Battery caution

Misuse of Li-ion batteries may result in the following

hazards: smoke, re, or the battery may rupture. Misuse

can also cause damage to the battery or degradation of
battery performance.

R DANGER! NEVER solder the battery terminals, or NEVER
modify the battery pack. This may cause heat generation, and

the battery may burst, emit smoke or catch re.

R DANGER! NEVER place or leave battery packs in areas
with temperatures above 60°C (140°F). High temperature

buildup in the battery cells, such as could occur near res or

stoves, inside a sun-heated vehicle, or in direct sunlight for
long periods of time may cause the battery cells to rupture

or catch re. Excessive temperatures may also degrade the

battery pack’s performance or shorten the battery cell’s life.
R DANGER! NEVER strike or otherwise impact the battery

pack. Do not use the battery pack if it has been severely
impacted or dropped, or if the pack has been subjected to
heavy pressure. Battery pack damage may not be visible
on the outside of the case. Even if the surface of the battery
does not show cracks or any other damage, the cells inside

the battery may rupture or catch re.

R DANGER! NEVER expose the battery pack to rain, snow,
seawater, or any other liquids. Do not charge or use a wet
pack. If the pack gets wet, be sure to wipe it dry before using.

R DANGER! NEVER place or leave battery packs near re.
Fire or heat may cause them to rupture or explode. Dispose
of used battery packs in accordance with local regulations.

R DANGER! NEVER let uid from inside the battery get in
your eyes. This can cause blindness. Rinse your eyes with
clean water, without rubbing them, and immediately go to a
doctor.

R WARNING! NEVER put the battery pack in a microwave
oven, high-pressure container, or in an induction heating

cooker. This could cause a re, overheating, or cause the

battery cells to rupture.
R WARNING! NEVER use the battery pack if it emits an

abnormal odor, heats up, or is discolored or deformed. If
any of these conditions occur, contact your Icom dealer or
distributor.

R WARNING! NEVER Iet uid from inside the battery cells
come in contact with your body. If it does, immediately wash
with clean water.

CAUTION: DO NOT use the battery pack out of the

specied temperature range for the transceiver (–30°C
~ +60°C (–22°F ~ +140°F)) and the battery itself (–20°C
~ +60°C (–4°F ~ +140°F)). Using the battery out of its
specied temperature range will reduce its performance and

battery cell’s life. Please note that the specied temperature
range of the battery may exceed that of the transceiver. In
such cases, the transceiver may not work properly because
it is out of its operating temperature range.

7

BATTERY CHARGING

4

CAUTION: DO NOT leave the pack fully charged,
completely discharged, or in an excessive temperature
environment (above 50°C, 122°F) for an extended period of
time. If the battery pack must be left unused for a long time,
it must be detached from the transceiver after discharging.
You may use the battery pack until the remaining capacity is
about half, then keep it safely in a cool and dry place at the
following temperature range:

–20°C ~ +50°C (–4°F ~ +122°F) (within a month)
–20°C ~ +40°C (–4°F ~ +104°F) (within three months)
–20°C ~ +20°C (–4°F ~ +68°F) (within a year)

BE SURE to replace the battery pack with a new one

approximately ve years after manufacturing, even if it still

holds a charge. The material inside the battery cells will
become weak after a period of time, even with little use.
The estimated number of times you can charge the pack
is between 300 and 500. Even when the pack appears to
be fully charged, the operating time of the transceiver may
become short when:

• Approximately 5 years have passed since the pack was

manufactured.

• The pack has been repeatedly charged.

The battery cells may deteriorate and swell due to their
characteristics if used in an environment and conditions such as:
frequently charged, echarged immediately after full charge, used
or saved in a hot place, or charged by methods other than the
instructions. If the battery pack swells, it has reached the end of
its life due to deterioration. Replace it with a brand new one.

■ Charging caution

R DANGER! NEVER charge the battery pack in areas with

extremely high temperatures, such as near res or stoves,

inside a sun-heated vehicle, or in direct sunlight. In such
environments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.

R WARNING! NEVER charge the transceiver during a
lightning storm. It may result in an electric shock, cause a

re or damage the transceiver. Always disconnect the power

adapter before a storm.
R WARNING! NEVER charge or leave the battery in the

battery charger beyond the specied time for charging. If the
battery is not completely charged by the specied time, stop

charging and remove the battery from the battery charger.

Continuing to charge the battery beyond the specied time
limit may cause a re, overheating, or the battery may

rupture.
R WARNING! NEVER insert the transceiver (battery

attached to the transceiver) into the charger if it is wet or
soiled. This could corrode the battery charger terminals or
damage the charger. The charger is not waterproof.

CAUTION: DO NOT charge the battery outside of the

specied temperature range: BC-227 (15˚C ~ 40˚C
(59˚F ~ 104˚F)). Otherwise, the charging time will be longer,

but the battery will not reach a full charge. While charging,

at a point after the temperature goes out of the specied

range, the charging will automatically stop.

INFORMATION

CAUTION

13

To ensure that your expose to RF
electromagnetic energy is within the FCC
allowable limits for occupational use, always
adhere to the following guidelines:

• DO NOT operate the radio without a proper antenna
attached, as this may damage the radio and may also
cause you to exceed FCC RF exposure limits. A proper
antenna is the antenna supplied with this radio by the

manufacturer or an antenna specically authorized by the

manufacturer for use with this radio.

• DO NOT transmit for more than 50% of the total radio
use time (“50% duty cycle”). Transmitting more than 50%
of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmitting
when “TX” is displayed on the function display. You can
cause the radio to transmit by pushing the “PTT” switch.

• ALWAYS keep the antenna at least 2.5 cm (1 inch) away
from the body when transmitting, and only use the Icom
belt-clips listed on page 24 when attaching the radio
to your belt, or other place, to ensure FCC RF exposure
compliance requirements are not exceeded.

The information listed above provides the user with the
information needed to make him or her aware of RF
exposure, and what to do to assure that this radio operates
within the FCC RF exposure limits of this radio.

Electromagnetic Interference/Compatibility

During transmissions, your Icom radio generates RF energy
that can possibly cause interference with other devices or
systems. To avoid such interference, turn off the radio in
areas where signs are posted to do so. DO NOT operate
the transmitter in areas that are sensitive to electromagnetic
radiation such as hospitals, aircraft, and blasting sites.

Occupational/Controlled Use

The radio transmitter is used in situations in which persons
are exposed as a consequence of their employment,
provided those persons are fully aware of the potential for
exposure and can exercise control over their exposure.
