RWARNING RF EXPOSURE!

This device emits
Radio Frequency (RF) energy. Caution should be observed
when operating this device. If you have any questions re­garding RF exposure and safety standards please refer to the
Federal Communications Commission Office of Engineering
and Technology’s report on Evaluating Compliance with FCC
Guidelines for Human Radio Frequency Electromagnetic
Fields (OET Bulletin 65)

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 (2
to 4 inches) away from the lips and the transceiver is vertical.

RWARNING! NEVER operate the transceiver with a

earphone, headphones or other audio accessories at high
volume levels. Hearing experts advise against continuous
high volume operation. If you experience a ringing in your
ears, reduce the volume level or discontinue use.

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 16 V DC. This will ruin the transceiver.

NEVER connect the transceiver to a power source using

reverse polarity. This will ruin the transceiver.

NEVER expose the transceiver to rain, snow or any liquids.

The transceiver may be damaged.

NEVER operate or touch the transceiver with wet hands.

This may result in an electric shock or damage the trans­ceiver.

DO NOT operate the transceiver near unshielded electri-

cal blasting caps or in an explosive atmosphere.

DO NOT push the PTT when not actually desiring to transmit.
BE CAREFUL! The transceiver will become hot when op-

erating it continuously for long periods.

AVOID using or placing the transceiver in direct sunlight or

in areas with temperatures below –20°C (–4˚F) or above
+60°C (+140˚F).

Place the unit in a secure place to avoid inadvertent use by
children.

AVOID the use of chemical agents such as benzine or al-

cohol when cleaning, as they can damage the transceiver’s
surfaces.

For U.S.A. only

■ Caution

• R DANGER! Use and charge only specified Icom battery

packs with Icom radios. Only Icom battery packs are tested
and approved for use with Icom radios. Using third-party or
counterfeit battery packs may cause smoke, fire, or cause
the battery to burst.

DD

Battery caution

• R DANGER! DO NOT hammer or otherwise impact the bat-

tery. Do not use the battery if it has been severely impacted
or dropped, or if the battery has been subjected to heavy
pressure. Battery 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 fire.

• R DANGER! NEVER use or leave battery pack in areas

with temperatures above +60˚C (+140˚F). High temperature
buildup in the battery, such as could occur near fires or
stoves, inside a sun heated car, or in direct sunlight may
cause the battery to rupture or catch fire. Excessive temper­atures may also degrade battery performance or shorten
battery life.

• R DANGER! DO NOT expose the battery to rain, snow,

seawater, or any other liquids. Do not charge or use a wet
battery. If the battery gets wet, be sure to wipe it dry before
using. The battery is not waterproof.

• R DANGER! NEVER incinerate an used battery pack since

internal battery gas may cause it to rupture, or may cause
an explosion.

• 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 fire.

• R DANGER! Use the battery only with the transceiver for

which it is specified. Never use a battery with any other
equipment, or for any purpose that is not specified in this in­struction manual.

• R DANGER! If fluid from inside the battery gets in your

eyes, blindness can result. Rinse your eyes with clean
water, without rubbing them, and see a doctor immediately.

• WARNING! Immediately stop using the battery 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.

• WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside the
battery.

Misuse of Lithium-Ion batteries may result in the follow­ing hazards: smoke, fire, or the battery may rupture.
Misuse can also cause damage to the battery or degra­dation of battery performance.

• WARNING! NEVER put the battery in a microwave oven,
high-pressure container, or in an induction heating cooker.
This could cause a fire, overheating, or cause the battery to
rupture.

• CAUTION! Always use the battery within the specified tem-
perature range, –20˚C to +60˚C (–4˚F to +140˚F). Using the
battery out of its specified temperature range will reduce the
battery’s performance and battery life.

• CAUTION! Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an excessive
temperature environment (above +50˚C; +122˚F) for an ex­tended period of time. If the battery must be left unused for a
long time, it must be detached from the radio after discharg­ing. You may use the battery until the battery indicator
shows half-capacity, then keep it safely in a cool dry place
with the temperature between –20˚C to +20˚C (–4˚F to
+68˚F).

DD

Charging caution

• R DANGER! NEVER charge the battery pack in areas with

extremely high temperatures, such as near fires or stoves,
inside a sun heated car, or in direct sunlight. In such envi­ronments, the safety/protection circuit in the battery will acti­vate, causing the battery to stop charging.

• WARNING! DO NOT charge or leave the battery in the bat-
tery charger beyond the specified time for charging. If the
battery is not completely charged by the specified time, stop
charging and remove the battery from the battery charger.
Continuing to charge the battery beyond the specified time
limit may cause a fire, overheating, or the battery may rup­ture.

• 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 spec-
ified temperature range: 0˚C to +35˚C (+32˚F to +95˚F).

The indicators show “ ,” “ ” and “ ” in sequence
while charging, and both indicators disappear when com­pletely charged.

DD

Charging note

• Be sure to turn the transceiver power OFF.

Otherwise the battery pack will not be charged completely or takes
longer charging time periods.

• External DC power operation becomes possible when using
an optional CP-12L, CP-19R or OPC-254L. The attached
battery pack is also charged simultaneously, except during
transmit. (see p. 11 for more details)

• The external DC power supply voltage must be within
10–16 V to charge the battery pack and operation when
using an optional OPC-254L.

■ Rapid charging

The optional BC-139 provides rapid charging of the battery
pack.

• Charging period: 2.5 hours (with BP-217)

DD

Charging note

• Be sure to turn the transceiver power OFF.
Detach the battery pack from the transceiver then charge
the battery pack by itself, or charge the battery with regular
charging when the transceiver power cannot be turned OFF.
Otherwise the battery pack will not be charged

(charging indi-

cator on the BC-139 blinks orange).

• The desktop charger, BC-139, can only be charged BP-217.
Other types of rechargeable battery, Ni-Cd or Ni-MH, can­not be charged.

• If the charging indicator blinks orange, there may be a prob­lem with the battery pack

(or charger). Reinsert the battery

pack or contact your dealer.

• The optional CP-12L, CP-19R and OPC-254L can be used
instead of the supplied AC adapter

(BC-123). Connect one of

these to the [AC ADAPTER] jack in this case.

■ Optional battery case

➥ Install 2 R6 (AA) size alka-

line batteries into the op­tional BP-216

BATTERY

CASE

.

• Be sure to observe the cor­rect polarity.

A built-in step-up convertor in the BP-216 increases the
voltage to 5 V DC.

Approx. 100 mW of output power is possible with the BP-

216 operation. Also, no transmit output power selection is
available.

Keep battery contacts clean. It’s a good idea to clean bat­tery terminals once a week.

D Battery information

The batteries may seem to have low capacity when used in
low temperatures such as –10°C

(+14°F) or below. Keep the

battery case or pack warm in this case.

D Battery replacement

When the batteries become exhausted, the function display
may blink or have a lower contrast. In these cases, replace
all batteries with new, same brand, alkaline batteries.

■ Battery information

DD

Battery life

The transceiver operates with the BP-217 as follows.
However, when operating in DV mode, operating time may be
shortened by one-half hour.

• VHF band : Approx. 5 hours

• UHF band : Approx. 4.5 hours

(Tx: Rx: Stand-by=1: 1: 8)

Even when the transceiver power is OFF, a slight current
still flows in the circuits. Remove the battery pack or case
from the transceiver when not using it for a long time. Oth­erwise, the battery pack or installed batteries will become
exhausted.

DD

Battery indicator

The battery indicator, “ ,” appears only when the BP-217
is attached to the transceiver.

The battery indicator does not appear when turning power
ON after the charging is completed without disconnecting
the battery charger or external DC power.

Indication Battery condition

The battery has ample capacity.

The battery is nearing exhaustion. Charging is neces­sary.

■ External DC power operation

An optional cigarette lighter cable (CP-12L or CP-19R; for 12 V

cigarette lighter socket) or external DC power cable (OPC-254L)

can be used for external power operation.

DD

Operating note

• Power supply range is between 10.0–16.0 V DC.
NEVER CONNECT OVER 16 V DC directly into the [DC IN]

jack of the transceiver.

• BE SURE to use CP-12L,CP-19R or OPC-254L when con­necting a regulated 12 V DC power supply.
Use an external DC-DC converter to connect the transceiver
through optional CP-12L, CP-19R or OPC-254L to a 24 V
DC power source.

• The voltage of the external power supply must be within
10–16 V DC when using either CP-12L, CP-19R or OPC­254L, otherwise, use the battery pack.

• Up to 5 W

(approx.) of maximum output power is provided

with the external DC power operation, however, when the
supplied voltage exceeds 14 V, the built-in protection circuit
activates to reduce the transmit output power to 0.5 W

(ap-

prox.).

• Disconnect the power cables from the transceiver when not
using it. Otherwise, the vehicle battery will become ex­hausted.

• The power save function is deactivated automatically during
external DC power operation.
