Battery information
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 compatible 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.
Never use any charger that is damaged.
