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.
15. 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.
16. This apparatus must be earthed.
17. 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).
