Projection Lens
To avoid the risk of scratching the

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.
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.
