it from a cold location to a hot location. When the
projector is exposed to such a change in temperature,
moisture may condense on the crucial internal parts. To
prevent the projector from possible damage, do not use
the projector for at least 2 hours when there is a sudden
change in temperature.

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 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.
