4 Important safety instructions
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.
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 (if any) or
remove the lens cap (if any) when the
projector lamp is on.
5. The lamp becomes extremely hot during
operation. Allow the projector to cool for
approximately 45 minutes prior to removing
the lamp assembly for replacement.
6. 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).
7. 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, use the
blank function.
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.

5Important safety instructions
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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.

6 Important safety instructions
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 power
outlet and call BenQ to have the projector
serviced.
18. This product is capable of displaying inverted
images for ceiling/wall mount installation.
19. This apparatus must be earthed.
20. 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, shorten
the projector's life span and darken 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).
Hg - Lamp contains mercury. Manage in accordance with local disposal laws. See www.lamprecycle.org.
To avoid damaging the DLP chips, never aim a high-power laser beam into the projection lens.
