15.3 Maintaining Your Device

Taking good care of your device will ensure trouble-free operation and reduce the
risk of damage to your device.
Keep your device away from excessive moisture and extreme temperatures.
Avoid exposing your device to direct sunlight or strong ultraviolet light for
extended periods of time.
Do not place anything on top of your device or drop objects on your device.
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.
Take care not to sit on the device. We advise not to carry the device in one's
back pocket for that reason.
The screen surface can easily be scratched. Avoid touching it with sharp
objects. Non-adhesive generic screen protectors designed specifically for use
on portable devices with LCD panels may be used to help protect the screen
from minor scratches.
Never clean your device with it powered on. Use a soft, lint-free cloth to wipe
the screen and the exterior of your device.
