Nokia HS 54W ユーザーズマニュアル

Your device is powered by a rechargeable battery. The full performance of a new battery is 
achieved only after two or three complete charge and discharge cycles. The battery can be 
charged and discharged hundreds of times, but it will eventually wear out. Recharge your 
battery only with Nokia approved chargers designated for this device.

Unplug the charger from the electrical plug and the device when not in use. Do not leave a 
fully charged battery connected to a charger, since overcharging may shorten its lifetime. If 
left unused, a fully charged battery will lose its charge over time.

Use the battery only for its intended purpose. Never use any charger or battery that is 
damaged.

Leaving the device in hot or cold places, such as in a closed car in summer or winter 
conditions, will reduce the capacity and lifetime of the battery. Always try to keep the 
battery between 15°C and 25°C (59°F and 77°F). A device with a hot or cold battery may not 
work temporarily, even when the battery is fully charged. Battery performance is particularly 
limited in temperatures well below freezing.

Do not dispose of batteries in a fire as they may explode. Batteries may also explode if 
damaged. Dispose of batteries according to local regulations. Please recycle when possible. 
Do not dispose as household waste.
