7 CLEANING
The touch screen should be kept as clean as possible to preserve
optical properties. Attempt to keep the screen free of dirt, dust
fingerprints, etc. long term contact with abrasive materials will scratch
the surface, and impair image quality. To clean, use a damp
nonabrasive cloth towel and any commercially available window
cleaner. The cleaning solution should be applied to the towel rather
than the surface of the touch screen.
The case is made out of durable ABS plastic. It can be cleaned with a
damp cloth and a mild detergent. Do not use chemical solvents on
the case.
