ladder.

l
Before you clean the projector, press the Power button twice on the remote control to
put the system in Standby mode and then wait 30 minutes for the lamp to cool completely.
l
Never touch the lens or the mirror with your hands or a brush.
l
Do not allow liquids or commercial solvents of any kind to flow into the projector base or
head.
Do not spray cleaners or solvents near any part of the projector because they can spread a
chemical mist on some of the projector’s components and lamp, resulting in damage,
staining or poor image quality.
l
Do not use compressed air to clean the projector.
When cleaning the projector’s lens or mirror:
l
Use a bellows bulb or air blower bulb (commonly found in audio-visual supply stores) to blow
off dust.
l
If wiping the lens or mirror is unavoidable, wear protective gloves and gather the cleaning
cloth into a ball. Gently fan the cleaning cloth across the lens or mirror as you would a
feather duster. Do not apply any pressure to the lens or mirror.
