– when using, charging, or storing the battery in high temperature
condition
To avoid hastening the deterioration of the battery pack thereby
prolonging its useful life, minimize the number of times you charge it so
as not to frequently increase its internal temperature.
Charge the battery pack between 10 °C ~ 30 °C (50 °F ~ 86 °F) temperature
range. A low temperature will prolong the charging time as well as
hasten the discharge time. A higher environment temperature will cause
the battery pack’s temperature to rise. Avoid charging the battery pack
inside a closed vehicle and in hot weather condition. Also, charging will
not start if the battery pack is not within the allowed temperature range.
It is recommended that you do not charge the battery pack more than
once a day.
It is recommended that you charge the battery pack with the Tablet PC’s
power off.
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 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.
Use a soft cloth to remove dirt on the display. The touchscreen surface
has a special protective coating that prevents dirt from sticking to it. Not
using a soft cloth may cause damage to the special protective coating on
the touchscreen surface.
Turn off the Tablet PC power when cleaning the display. Cleaning the
display with the power on may cause improper operation.
