 Important guidelines when using the battery pack.
When installing or removing the battery pack take note of the following:
– avoid installing or removing the battery pack when the Tablet PC is
in Sleep mode. Abruptly removing the battery pack may cause
loss of data or the Tablet PC may become unstable.
– avoid touching the battery pack terminals or damage may occur,
thereby causing improper operation to it or the Tablet PC.
The Tablet PC’s input voltage and surrounding temperature will directly
affect the battery pack’s charge and discharge time:
– charging time will be prolonged when the Tablet PC is turned on.
To shorten the charging time, it is recommended that you place the
Tablet PC in Sleep or Hibernation mode.
– a low temperature will prolong the charging time as well as hasten
the discharge time.
 When using battery power in an extremely low temperature
environment, you may experience shortened operating time and
incorrect battery level reading. This phenomenon comes from the
chemical characteristics of batteries. The appropriate operating
temperature for the battery is -10 °C ~ 50 °C (14 °F ~ 122 °F).
 Do not leave the battery pack in storage for more than six months
without recharging it.
Touchscreen Guidelines
 Use the finger or the included stylus on the display. Using a sharp or
metallic object other than your finger or stylus may cause scratches and
damage the display, thereby causing errors.
