BATTERY CHARGING 4 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 transceiver after discharging. You may use the battery until the remaining capacity is about half, then keep it safely in a cool dry place with the temperature range as below: -20˚C to +50˚C (-4˚F to +122˚F) (within a month) -20˚C to +35˚C (-4˚F to +95˚F) (within three months) BE SURE to replace the battery pack with a new one approximately five years after purchasing, 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 charging and discharging cycles is between 300 and 500, depending on the type of operation. Even when the battery appears to be fully charged, the operating time of the transceiver may become short when: • Approximately five years have passed since the battery was manufactured. • The battery has been repeatedly charged. DDCharging 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. R WARNING! NEVER charge the transceiver during a lightning storm. It may result in an electric shock, cause a fire 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 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. 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: NEVER charge the battery outside of the specified temperature range: BC-160/BC-171 (0˚C to +45˚C; +32˚F to +113˚F). BC-119N/BC-121N/BC-197 (+10˚C to +40˚C; +50˚F to +104˚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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 12
