Safety instructions for ceiling mounting of the
projector
We want you to have a pleasant experience using your projector, so we need to bring this
safety matter to your attention to prevent damage to person and property.
If you intend to mount your 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.
