about your projector.
Important Safety Instructions
Follow these safety instructions when setting up and using the projector:
■ Do not look into the lens when the projector is on. The bright light can
damage your eyes.
■ Do not place the projector on an unstable cart, stand, or table.
■ Do not operate the projector on its side, or while tilted to one side.
Do not tilt the projector forward or back at a greater angle than that
specified for keystone correction (see page 101).
■ If the projector is mounted on a ceiling, it should be installed by
qualified technicians using mounting hardware designed for use with
this projector.
■ If you use a ceiling mount and apply adhesives to the mount to prevent
the screws from loosening, or if you use lubricants or oils on the
projector, the projector case may crack and the projector may fall from
its ceiling mount. This could cause serious injury to anyone under the
mount and could damage the projector. When installing or adjusting a
ceiling mount, do not use adhesives to prevent the screws from loosening
and do not use oils or lubricants.
■ Do not stand on the projector or place heavy objects on it.
■ Do not use the projector where it may be exposed to rain, water, or
excessive humidity.
■ Unplug the projector from the wall outlet before cleaning. Use a dry
cloth (or, for stubborn dirt or stains, a moist cloth that has been wrung
dry) for cleaning. Do not use liquid or aerosol cleaners.
■ Never spill liquid of any kind into the projector.
■ Do not use the projector where it may be exposed to excessive dust or
smoke.
