Safety Precautions - Ceiling Mounting
Please read the following Safety Precautions before you start using the projector.
If you intend to mount the projector on the ceiling, we strongly recommend
that you use a proper fitting projector ceiling mount kit and that you ensure it is
securely and safely installed.
If you use an inappropriate projector ceiling mount kit, there is a safety risk that the
projector may fall from the ceiling due to an improper attachment through the use
of the wrong gauge or length screws.
You can purchase a projector ceiling mount kit from the place you purchased your
projector. We recommend that you also purchase a separate security cable and
attach it securely to both the anti-theft lock slot on the projector and the base of
the ceiling mount bracket. This will perform the secondary role of restraining the
projector should its attachment to the mounting bracket become loose.
