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 the lens only if absolutely required.
Remove Dust
1. Brush most of the dust off with a camelhair brush or use a dust-free blower.
2. Fold a microfiber 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 camelhair 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.
Inspect the Card Cage Filter
Use only high efficiency Christie approved filters. Never operate the projector without the filter
installed.
You should check the condition of the card cage air filter monthly. Clean or replace the card cage air
filter sooner if you are operating the projector in a dusty or dirty environment. The filter is located on
the left side of the projector behind the air filter cover.
1. Loosen the 2 captive screws on the bottom of the filter cover.
2. Pull the cover out and down.
3. Slide the air filter out and inspect it.
