Caring for Your Tablet Device
Tablet device
Make sure you close any connector covers and keep them secure.
Clean the cabinet with a soft, dry or slightly moistened cloth with a mild detergent solution. Do not use a detergent solution for
cleaning the touch screen. Do not use an abrasive pad, scouring powder, or solvent such as alcohol or benzine, as these may
damage the finish of your tablet device.
If your tablet device is exposed to moisture such as rain or extreme humidity, wipe your tablet device with a soft dry cloth, but do
not dry with an oven or dryer.
Built-in camera
Clean the lens protection cover of the built-in camera with a blower brush or a soft brush. If the cover is extremely dirty, wipe it off
with a soft dry cloth. Do not rub the cover, as it is sensitive to pressure.
