The information in this chapter is a guide to the cleaning and maintenance of your Projection Panel, as well as to locating and solving possible problems.

5.1Cleaning the Display Surface

1.Handle the Projection Panel as you would anything made of glass. Be especially careful not to drop it.

The hardened polymer surface of the Real Color 16 LCD Projection Panel (AC400A) is designed to be scratch and dent resistant. However, you should avoid scratching it with sharp metal objects.

2.If the surface needs cleaning, you can use any normal non- abrasive glass cleaner on it.

Apply the cleaner to a cleaning cloth and then wipe the surface lightly. Do not use excessive amounts of liquid. Do not use abrasive cleaners, solvents, or other harsh chemicals.
