NEVER touch or blow on the panels.
To avoid the risk of scratching the lens,
only clean the lenses if absolutely
required. A small amount of dust on the
lenses will have very little effect on
picture quality. The projection lens
should be free of dust and fingerprints.
If the lenses must be cleaned, use a
DRY soft cotton cloth. Rub gently in a
circular motion.
Section 2: Service Guidelines
Blow off particles with clean, dry de-
ionized air.
Use filtered compressed air to blow out
dust. Remove fingerprints or dirt with
Melles Griot Cleaning Fluid 18LAB011 (or
equivalent) and a clean lint-free cloth.
