The service manual when downloaded and printed out was clear and easy to read. The manual is complete with the schematic diagram and technical data. I occasionally require a manual and now having registered with this company I shall order from them in the future.

Before Using (continued)
Cleaning
To ensure continued excellent performance from this product, periodic cleaning is recommended.
Projection Display
The unit contains many plastic parts. For this reason DO NOT use benzine, thinner or other chemicals to clean the unit.
DO NOT bring into contact with insecticide or other volatile substances. DO NOT allow the unit to come into contact for extended periods with rubber or vinyl products.
Remove dirt and soiling by wiping with a light cloth. Even if the unit is heavily soiled, do not apply cleaner directly to the unit. Soak a cloth in a solution of neutral cleanser diluted with water. Then wring out the cloth, wipe the unit clean, and finish by wiping with a dry cloth. Do not use any type of cleansers on the picture screen. Picture Screen Dust will accumulate on the picture screen. Please wipe with a soft cloth from time to time. If you use a chemically treated cloth, please be careful to follow the instructions that come with the cloth.
