Maintenance
Avoid exposing your device to direct sunlight or strong
ultraviolet light for extended periods of time.
Do not drop your device or subject it to severe shock.
Do not subject your device to sudden and severe
temperature changes. This could cause moisture
condensation inside the unit, which could damage your
device. In the event of moisture condensation, allow the
device to dry out completely before use.
The screen surface can be easily scratched. Sharp objects
may scratch the screen. You may use non-adhesive
generic screen protectors designed specifically for use on
portable devices with LCD panels to help protect the
screen from minor scratches.
Never clean your device when it is powered on.
Never use organic solvents such as benzene or paint
thinner to clean your device. Use of these solvents can
cause deformation or discoloration.
Use a soft, clean, lint-free cloth to clean the display screen.
Moistened LCD screen wipes could also be used as
required.
Never attempt to disassemble, repair or make any
modifications to your device. Disassembly, modification or
any attempt at repair could cause damage to your device
and even bodily injury or property damage and will void
any warranty.
