Important safety instructions 3
Important safety instructions
Your projector 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.
Safety Instructions
1. Please read this manual before
you operate your projector.
Save it for future 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. Always open the lens shutter
or remove the lens cap when
the projector lamp is on.
5. 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).
6. 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.
Important safety instructions4
Safety Instructions (Continued)
7. The lamp becomes extremely hot
during operation. Allow the
projector to cool for
approximately 45 minutes prior
to removing the lamp assembly
for replacement.
8. 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.
9. Never replace the lamp assembly
or any electronic components
unless the projector is unplugged.
10. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining
serious damage.
11. 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.
Under no circumstances should
you ever undo or remove any
other covers. Refer servicing only
to suitably qualified professional
service personnel.
12. 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.

Safety Instructions (Continued)
13. Do not place this projector in any of
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).
14. Do not block the ventilation holes.
- Do not place this projector on a
blanket, 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.
15. 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.

Safety Instructions (Continued)
16. 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.
17. 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.
18. 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.
19. 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.
