Important safety instructions 5
Important safety instructions
Your BenQ 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. To
temporarily turn off the lamp, press
BLANK on the projector or remote
control.

Important safety instructions6
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. 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.

Safety Instructions (Continued)
12. 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 10000 feet.
13. 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.
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.

Safety Instructions (Continued)
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.
19. 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.
