Important safety instructions
Your pr ojector is designed and tested to meet the latest standards for safety of information
technology equipment. However, to ensure safe use of this product, it is important that
you follow the instructions mentioned in this manual and marked on the product.
1. Please read this manual before
you operate your projector. Save
it for fut ure reference.
2. Do not look straight at the
projector lens during operation.
The intense light beam may damage
your eyes.
3. Refer servicing to qualified
service personnel.
4. In some countries, the line voltage is
NOT stable. This projector is
designed to operate safely within a
mains voltage between 100 to 240
volts AC, but could fail if power cuts
or surges of ±10 volts occur . In areas
where the mains voltage may
fluctuate or cut out, it is
recommended that you connect
your projector through a power
stabilizer, surge protector or
uninterruptible power supply
(UPS).
5. Do not block the projection lens with
any objects when the projector is
under operation as this could cause
the objects to become heated and
deformed or even cause a fire. To
temporarily turn off the lamp, press
BLANK on th e remot e control.
Important safety instructions 3
6. The lamp becomes extremely hot
during operation. Allow the projector
to cool for approximately 45 minutes
prior to removing the lamp assembly
for replacement.
7. Do not operate lamps beyond the
rated lamp life. Excessive operation of
lamps beyond the rated life could
cause them to break on rare
occasions.
8. Never repl ace the lamp assembly or
any electronic components unless the
projector is unplugged.
9. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.
10. 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 the lamp which has its own
removable cover.
Under no circumstances should you
ever undo or remove any other
covers. Refer servicing only to suitably
qualified professional service
personnel.
11. When the projector is under
operation, you may sense some
heated air and odor from its
ventilation grill. It is a normal
phenomenon and not a product
defect.
Important safety instructions4
12. Do not place this projector in any of
3000 m
(10000 feet)
0 m
(0 feet)
the following environments.
- Space that is poorly ventilated or
confined. Allow at least 50 cm clearance
from walls and free flow of air around
the projector.
- Locations where temperatures may
become excessively high, such as the
inside of a car with all windows rolled
up.
- Locations where excessive humidity,
dust, or cigarette smoke may
contaminate optical components,
shortening the projector's life span and
darkening the image.
- Locations near fire alarms
- Locations with an ambient temperature
above 40°C / 104°F
- Locations where the altitudes are higher
than 3000 m (10000 feet).
13. Do not block the ventilation holes.
- Do not place this projector on a b lank et,
bedding or any other soft surface.
- Do not cover this projector with a cloth
or any other item.
- Do not place inflammables near the
projector.
If the ventilation holes are seriously
obstructed, overheating inside the
projector may result in a fire.
14. Always place the projector on a level,
horizontal surface during operation.
- Do not use if tilted at an angle of more
than 10 degrees left to right, nor at angle
of more than 15 degrees front to back.
Using the projector when it is not fully
horizontal may cause a malfunction of,
or damage to, the lamp.
15. Do not stand the projector on end
vertically. Doing so may cause the
projector to fall over, causing injury or
resulting in damage to the projector.
Important safety instructions 5
16. Do not step on the projector or place
any objects upon it. Besides probable
physical damage to the projector,
doing so may result in accidents and
possible injury.
17. Do not place liquids near or on the
projector. Liquids spilled into the
projector may cause it to fail. If the
projector does become wet,
disconnect it from the power supply's
wall socket and call BenQ to have the
projector serviced.
18. This product is capable of displaying
inverted images for ceiling mount
installation.
Use only BenQ's Ceiling Mount Kit for
mounting the projector and ensure it
is securely installed.
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 pr ojector
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.
Hg - Lamp contains mercury . Manage
in accordance with local disposal
laws. See www.lamprecycle.org.

meters (~ 26 feet).
Make sure that there are no obstacles between the
remote control and the IR sensor on the projector that
might obstruct the infra-red beam.

There is 5% tolerance among these numbers due to optical component variations. BenQ
recommends that if you intend to permanently install the projector, you should physically test
the projection size and distance using the actual projector before you permanently install it, so
as to make allowance for this projector's optical characteristics. This will help you determine
the exact mounting position so that it best suits your installation location.
