PRECAUTIONS

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)

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 electrical blasting caps or in an explosive atmosphere.

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.

DO NOT push the PTT when not actually desiring to transmit.

BE CAREFUL! The transceiver will become hot when operating 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 alcohol when cleaning, as they can damage the transceiver’s surfaces.

For U.S.A. only

3 BATTERY CHARGING

■ Caution

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.

•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.

DBattery caution

•R DANGER! DO NOT hammer or otherwise impact the battery. 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.

8

•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 temperature 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).

BATTERY CHARGING 3

D Charging caution

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

3

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 battery 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 specified temperature range: 0˚C to +35˚C (+32˚F to +95˚F). Icom recommends charging the battery at +20˚C (+68˚F). The battery may heat up or rupture if charged out of the specified temperature range. Additionally, battery performance or battery life may be reduced.

3 BATTERY CHARGING

■ Optional battery case

Install 2 R6 (AA) size alkaline 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 bat- tery 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

D 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. Oth- erwise, the battery pack or installed batteries will become exhausted.

D 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.

BATTERY CHARGING 3

■ 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.

Transceiver

D 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 (approx.).

•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.

■ Operating mode selection

Operating modes are determined by the modulation of the radio signals. The transceiver has total 5 operating modes (A band: FM, WFM and AM modes, B band FM, FM-N, AM and DV modes). The mode selection is stored independently for each band and memory channel.

Typically, AM mode is used for the AM broadcast stations (0.495–1.620 MHz) and air band (118–136.995 MHz), and WFM is used for FM broadcast stations (76–107.9 MHz).

WFM mode cannot be selected above 810 MHz for USA version.

Push and hold [MODE](REC) for 1 sec. several times to select the desired operating mode.
