Battery charging notice
The battery may not begin charging immediately under the following
conditions:
The battery is extremely hot or cold (if the battery is extremely hot, it
might not charge at all). To ensure the battery charges to its full
capacity, you should charge it at room temperature of between 5°C to
35°C (41°F to 95°F).
The battery is nearly completely discharged. In this instance you
should leave the AC adaptor connected for a few minutes and the
battery should begin charging.
The indicator may show a rapid decrease in battery operating time when
you try to charge a battery under the following conditions:
The battery has not been used for a long time.
The battery has completely discharged and been left unattended for a
long time.
In such cases you should follow the steps as detailed below:
1.
Fully discharge the battery with the power on until the system
automatically turns itself off.
2. Connect the AC adaptor to the Micro USB port of the tablet, and to a
wall outlet that is supplying power.
3. Charge the battery until the multi function LED indicator (when it is set
as Power/battery indicator) is white.
Repeat these steps two or three times until the battery recovers normal
capacity.
