Notes on Charging
Charging the battery
For your safety, use only the supplied AC power cord (mains lead) to charge the battery.
Performance and safety are not guaranteed if you charge using an AC adapter other than the
AC adapter designed for the tablet device.
Depending on the ambient temperature or how you use your tablet device, the battery may not
be charged or it may take a long time to charge the battery.
Do not charge the battery near fire or in direct sunlight.
The tablet device is not fully charged when shipped.
Heat builds up in the battery while it is in use or being charged. This is normal and is not cause
of concern. If your tablet device or the AC adapter becomes abnormally hot, shut down your
tablet device and unplug the AC power cord (mains lead) from the AC adapter.
Battery discharge
After charging, the battery gradually loses its charge even if it is not used. If it is left unused for
a long time, the battery charge may be depleted. We recommend recharging the battery before
use.
If you do not use your tablet device for an extended period of time, fully charge the battery
every six months.

Battery life

Battery life varies depending on usage, settings, and temperatures.
Battery deterioration
Battery capacity gradually declines through repeated recharging and discharging. As a result,
the battery life may become short or the battery may not perform optimally even when fully
charged.
