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 the user manual / installation guide and marked on the product.
1.
Please read the user manual / installation guide 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 light source is on.
5. The light source becomes extremely hot during operation.
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 light source, use the blank function.
8. Do not operate light sources beyond the rated light source life.
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. 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.
13. 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.
14. 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.

If the projector does become wet, disconnect it from the power supply's power outlet and call
BenQ to have the projector serviced.
