Ceiling mounting the projector
We want you to have a pleasant experience using your BenQ projector, so we
need to bring this safety matter to your attention to prevent possible damage to
person and property.
If you intend to mount your projector on the ceiling, we strongly recommend
that you use a proper fitting BenQ projector ceiling mount kit and that you
ensure it is securely and safely installed.
If you use a non-BenQ brand 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 BenQ projector ceiling mount kit from the place you
purchased your BenQ projector. BenQ recommends that you also purchase a
separate Kensington lock compatible security cable and attach it securely to
both the Kensington 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.
