Important safety instructions
English
13. Never attempt to replace the lamp assembly
until the projector has cooled down and is
unplugged from the power supply.
14. When you think service or repair is required,
take the projector only to a suitably qualified
technician.
15. 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 parts are the lamp, and air filter
which have their own removable covers or
access panels. See pages 42 and 44.
Under no circumstances should you ever
undo or remove any other covers. Refer
servicing only to suitably qualified
professional service personnel.
Notice
Please keep the original packing for possible future
shipment. If you need to pack your projector after
use, adjust the projection lens to an appropriate
position, put the lens cushion around the lens, and
fit the lens cushion and projector cushion together
to prevent damage during transportation.
Moisture condensation
Never operate the projector immediately after moving
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.
Avoid volatile liquid
Do not use volatile liquids, such as insecticide or some
types of cleaner, near the projector. Do not have rubber
or plastic products touching the projector for a long
time. They will leave marks on the finish. If cleaning
with a chemically treated cloth, be sure to follow the
cleaning product’s safety instructions.
Disposal
This product contains the following materials which
are harmful to human bodies and environment.
Lead, which is contained in solder.
Mercury, which is used in the lamp.
To dispose of the product or used lamps, consult your
local environment authorities for regulations.
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.
