• R WARNING! Immediately stop using the battery if it emitsan abnormal odor, heats up, or is discolored or deformed. Ifany of these conditions occur, contact your Icom dealer ordistributor.• R WARNING! Immediately wash, using clean water, anypart of the body that comes into contact with fluid from in-side the battery.• R 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 batteryto rupture.• CAUTION: Always use the battery within the specified tem-perature range for the transceiver (–25˚C to +55˚C) and thebattery itself (–20˚C to +60˚C). Using the battery out of itsspecified temperature range will reduce the battery’s perfor-mance and battery life. Please note that the specified temper-ature range of the battery may exceed that of the transceiver.In such cases, the transceiver may not work properly be-cause it is out of its operating temperature range.• CAUTION: Shorter battery life could occur if the battery isleft fully charged, completely discharged, or in an excessivetemperature environment (above +50˚C) for an extendedperiod of time. If the battery must be left unused for a longtime, it must be detached from the radio after discharging.You may use the battery until the remaining capacity isabout half, then keep it safely in a cool dry place with thetemperature range as below:–20˚C to +50˚C (within a month)–20˚C to +35˚C (within three months)Charging cautionD• R DANGER! NEVER charge the battery pack in areas withextremely high temperatures, such as near fires or stoves,inside a sun heated car, or in direct sunlight. In such en-vironments, the safety/protection circuit in the battery willactivate, causing the battery to stop charging.• R WARNING! NEVER charge or leave the battery in thebattery charger beyond the specified time for charging. Ifthe battery is not completely charged by the specified time,stop charging and remove the battery from the battery char-ger. Continuing to charge the battery beyond the specifiedtime limit may cause a fire, overheating, or the battery mayrupture.• R WARNING! NEVER insert the transceiver (battery at-tached to the transceiver) into the charger if it is wet orsoiled. This could corrode the battery charger terminals ordamage the charger. The charger is not waterproof.• CAUTION: NEVER charge the battery outside of the speci-fied temperature range: BC-160 and BC-171 (0˚C to +45˚C),BC-119 and BC-121 (+10˚C to +40˚C). Icom recommendscharging the battery at +20˚C. The battery may heat up orrupture if charged out of the specified temperature range.Additionally, battery performance or battery life may be re-duced.204BATTERY CHARGING12345678910111213141516
