BATTERY CHARGING 3 • 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 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 remaining capacity is about half, and then keep it safely in a cool dry place at the following temperature range: -20˚C to +50˚C (-4˚F to +122˚F) (up to a month) -20˚C to +35˚C (-4˚F to +95˚F) (up to three months) -20˚C to +20˚C (-4˚F to +68˚F) (up to a year) 1 D Charging caution 2 • R DANGER! NEVER charge the battery pack in areas with 3 extremely high temperatures, such as near fires or stoves, inside a sun-heated vehicle, or in direct sunlight. In such 4 environments, the safety/protection circuit in the battery will 5 activate, causing the battery to stop charging. 6 • R WARNING! DO NOT charge or leave the battery in the battery charger beyond the specified time for charging. If 7 the battery is not completely charged by the specified time, stop charging and remove the battery from the battery char- 8 ger. Continuing to charge the battery beyond the specified 9 time limit may cause a fire, overheating, or the battery may rupture. 10 • R WARNING! NEVER insert the transceiver (battery at- 11 tached to the transceiver) into the charger if it is wet or 12 soiled. This could corrode the battery charger terminals or damage the charger. The charger is not waterproof. 13 • CAUTION: DO NOT charge the battery outside of the speci- 14 fied temperature range: BC-193 (+10˚C to +40˚C; +50˚F to +104˚F). Icom recommends charging the battery at +20˚C 15 (+68˚F). The battery may heat up or rupture if charged out 16 of the specified temperature range. Additionally, battery per- formance or battery life may be reduced. 17 18 19 10
