EXPLICIT DEFINITIONS
WORD DEFINITION
RDANGER! Personal death, serious injury or an
explosion may occur.
RWARNING! Personalinjury,rehazardorelectricshock
may occur.
CAUTION Equipment damage may occur.
NOTE
Ifdisregarded,inconvenienceonly.Noriskof
personalinjury,reorelectricshock.

CAUTION: DO NOT expose the transceiver to heavy rain, and
never immerse it in water. The transceiver meets IP57 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
withtemperaturesbelow–10°C(–14˚F)orabove+60°C(+140˚F).
Keep the transceiver in a secure place to prevent use by
unauthorizedpersons.
ii
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third-party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.
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:InCanada,useof8.33kHzChannelSpacingofthis
radio is strictly prohibited and shall not be used.
FCC caution:Changesormodicationstothistransceiver,not
expressly approved by Icom Inc., could void your authority to
operate this transceiver under FCC regulations. (USA only)

■Battery caution
RDANGER! 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.
RDANGER! 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.
RDANGER! 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.
RDANGER! 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.
RDANGER! 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.
RDANGER! 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.
RWARNING! 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.
RWARNING! 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.
RWARNING! 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 (–20°C
~ +60°C (–4°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.
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.

2BATTERY CHARGING
New2001
CAUTION: Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an excessive
temperature environment (above +60°C (+140°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 inside battery material will become
weak after a period of time, even with little use. The
estimated number of times you can charge the battery is
between 300 and 500. Even when the battery appears to
be fully charged, the operating time of the transceiver may
become short when:
• Approximately 5 years have passed since the battery was
manufactured.
• The battery has been repeatedly charged.
■Charging caution
RDANGER! 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.
RWARNING! 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.
RWARNING! 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.
RWARNING! 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: NEVER charge the battery outside of the
specied temperature range: BC-224 (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.
■Battery caution (continued)
CAUTION: It is better to replace the battery pack when the
battery’s health has declined.*
*A Caution dialog is displayed.
WARNING: Stop using the battery pack and replace it
when the battery’s health is critically low.*
*A Warning dialog is displayed.

rotating [DIAL] or accessing memory.
1. Push the Directional key to
display the “Recall CH” screen.
2. Select the channel.
• The selected channel will be set in 3
seconds.
LIt is not necessary to push [ENT]
to select the channel.
LPush [CLR] to return to the
previously selected frequency.
