Clean The Lens - Christie J series 2.0kW Service Manual

2.0.6 Clean the Lens

A small amount of dust or dirt on the lens has minimal effect on image quality. To avoid the risk of scratching
the lens, clean only if absolutely necessary.
Remove Dust:
1. Brush most of the dust off with a camel hair brush or use a dust-free blower.
2. Fold a microfibre cloth and wipe the remaining dust particles off the lens with the smooth portion of the
cloth that has no folds or creases. Do not apply pressure with your fingers. Instead, use the tension in the
folded cloth to remove the dust.
3. If significant dust remains on the lens surface, dampen a clean microfiber cloth with lens cleaning solution
and wipe gently until clean.
Remove Fingerprints, Smudges, or Oil:
1. Brush most of the dust off with a camel hair brush or use a dust-free blower.
2. Wrap a lens tissue around a swab and soak it in lens cleaning solution. The tissue should be damp but not
dripping.
3. Gently wipe the surface using a figure eight motion. Repeat until the blemish is removed.
