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.
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).
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.
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 light source, press the Eco Blank
button.
5. The light source becomes extremely hot
during operation. 8. Do not operate light sources beyond the
rated light source life.
5Important safety instructions
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.
Under no circumstances should you ever
undo or remove any other covers. Refer
servicing only to suitably qualified
professional service personnel.
11. 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.
12. Always place the projector on a level,
horizontal surface during operation.
13. 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.
14. 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.
15. 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.
16. 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.
6 Important safety instructions
17. This product is capable of displaying
inverted images for ceiling mount
installation.
18. This apparatus must be earthed.
19. 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).
