(on page 39).

2. Put on protective clothing and face shield.

3. Use the key to open the lamp door and access the lamp compartment.

Do not lean, or place heavy objects on the open lamp door.

4. Check the contact surfaces of the anode (positive) and the cathode (negative) connections for

cleanliness.

5. Clean electrical contact surfaces regularly to prevent contact resistance from scorching

connectors.

Use an approved contact cleaner.

6. Verify that all electrical and lamp connections are secure.

Removing dust from the lamp

Remove dust from the lamp to ensure optimum image brightness.

1. Brush most of the dust off with a camelhair brush or use a dust-free blower.

2. If some dust remains, leave it as some dust is inevitable.

Avoid unnecessary cleaning.

Removing ﬁngerprints, smudges, or oil from the lamp

R

emove fingerprints, smudge, or oil from the lamp to ensure optimum image brightness.

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 lamp with the smooth

portion of the cloth that has no folds or creases.

Do not apply finger pressure. Instead, use the tension in the folded cloth to remove the dust.

Inspecting and cleaning optics

Inspect and clean optical components such as the projection lens or reflector to ensure optimum

image display.

Unnecessary cleaning of optics can increase the risk of degrading delicate coatings and surfaces. The

reflector and projection lens may be inspected and cleaned as per the following instructions.

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.

Check: Monthly
