l Never touch the mirror with your hands or a brush, and do not scrub the surface of the mirror
with a cleaning cloth. Instead, use a cleaning cloth to clean the mirror with a light touch, and
do not put any cleaning solvents on the cloth or the mirror. Do not apply pressure to the
projector lens or mirror.
l 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 damage and poor image quality.
l Do not allow liquids or commercial solvents of any kind to flow into the projector base or
head.
