Caring for the Inside of the Projector
In order to ensure the safe use of your projector, please have it cleaned and inspected by an authorized Service
Provider approximately once every 2 years. Never try to care for the inside of the unit yourself. Doing so is
dangerous.
Caring for the Lens
Lightly wipe the lens with a commercially available lens-cleaning wipe. Do not touch the lens directly with
your hand.
Caring for the Cabinet and Remote Control Transmitter
Wipe lightly with gauze or a soft cloth. If soiling is severe, dip a soft cloth in water or a neutral cleanser
diluted in water, and wipe lightly after wringing well. Then, wipe lightly with a soft, dry cloth.
CAUTION:
• Make sure to turn off the power and unplug the power cord before caring for the unit. Please care-fully
• Do not use cleaners or chemicals other than those listed above, including benzene and paint thinner.
• Do not use aerosols or sprays.
• Do not polish or wipe with coarse material.
• Gently wipe with a soft cloth. If dirt and stains etc. are not easily removed, use a soft cloth dampened with
water, or water and a neutral detergent, and wipe dry with a soft, dry cloth.
