Important safety instructions
13. This projector is capable of displaying inverted
images for ceiling mount installation. Use only
BenQ's Ceiling Mount Kit for mounting.
Ceiling mounting the projector
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 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.
14. Do not attempt to disassemble this projector.
There are dangerous high voltages inside which
may cause death if you should come into contact
with live parts. The only user serviceable part is

Under no circumstances should you ever undo or
remove any other covers. Refer servicing only to
suitably qualified professional service personnel.
Please keep the original packing for possible
future shipment. If you need to pack your
