Cleaning the projector

WARNING

Cleaning a wall-mounted projector can result in a fall or injury. Use caution when
climbing a ladder, and consider removing the projector from its wall-mounting
bracket to clean it or to replace the projector lamp.

CAUTION

• Never touch the mirror with your hands or a brush, and do not scrub the
surface of the mirror with the supplied cleaning cloth. Instead, use the
supplied cleaning cloth to clean the mirror gently, and do not put any cleaning
solvents on the cloth or the mirror.

• Before you clean the projector, press the Power button twice on the Extended
Control Panel (ECP) or remote control to put the system into Standby mode,
and then allow the lamp to cool for at least 30 minutes.

• Do not spray cleaners, solvents or compressed air directly on the projector.
Do not use spray cleaners or solvents near any part of the projector because
they can damage or stain the unit. Spraying the system could spread a
chemical mist on some of the projector’s components and lamp, resulting in
poor image quality and damage to the product which may not be covered by
your warranty.

• Do not allow liquids or commercial solvents of any kind to flow into the
projector base or head.

IMPORTANT

• When cleaning the interactive whiteboard system:

– Wipe the exterior of the projector with a lint-free cloth.

PROJECTOR

– If necessary, use a soft cloth moistened with a mild detergent to clean the

projector housing.

– For optimum performance, clean the projector every 12 months. Increase

this frequency according to environmental conditions.

• Do not use abrasive cleaners, waxes or solvents.

• When cleaning the projector’s mirror:

– Use a bellows bulb or air blower bulb (commonly found in audio-visual

supply stores) to blow off dust. Never touch the mirror or lens with your
bare hands or a brush.

– If wiping the mirror or lens is unavoidable, wear protective gloves and

gather the supplied cleaning cloth into a ball. Gently run the cleaning cloth
across the mirror from the center to the edge, using the cleaning cloth like
you would a feather duster.

• When cleaning the projector’s lens:

– Never touch the lens with your bare hands or a brush.

– If wiping the lens is unavoidable, wear protective gloves and gather the

supplied cleaning cloth into a ball. Gently run the cleaning cloth across
the lens from the center to the edge, using the cleaning cloth like you
would a feather duster.

WARNING

• Replace the lamp when the projector displays its lamp life warning message.
If you continue to use the projector after this message appears, the lamp can
shatter or burst, scattering glass throughout the projector.

• If the lamp shatters or bursts, leave and then ventilate the area.

• Next do the following:

– Avoid touching the glass fragments because they can cause injury.

– Wash your hands thoroughly if you have come into contact with lamp

debris.

– Once the area has been ventilated, thoroughly clean the area around the

projector, and discard any edible items placed in that area because they
could be contaminated.

– Call your authorized SMART reseller

for instructions. Do not attempt to

replace the lamp.

• Uncovering the lamp while the projector is mounted on the wall-mounting
bracket can lead to product damage or personal injury from falling pieces of
glass if the lamp is broken.
