Battery care
Your device is powered by a rechargeable battery. When the power
is weak, please charge the battery. In order to extend the lifespan
of the battery, use all the battery's power before recharging.
Unplug the charger from the electrical plug and the device when
not in use. Do not leave the battery connected to a charger more
than a week. Overcharging may shorten its lifespan.
