Safety instructions
Your BenQ projector is designed and tested to meet the lastest 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. To reduce the risk of electric shock, do not disassemble this appliance. There are no user 
serviceable parts inside. Take it to a qualified technician when service or repair is required. 
Incorrect reassembly can cause malfunction of the projector or electric shock when the 
appliance is subsequently used. 
2. Please read this user’s manual before you operate your projector. Save this user’s manual for 
future reference.   
3. Refer servicing only to qualified service personnel.  
4. Always open the lens shutter or remove the lens cap when the projector lamp is on.  
5. Do not look straight at the projector lens during operation. The intense light beam may damage 
your eyes. 
6. In some countries, the line voltage is NOT stable. This projector is designed to operate safely 
with a mains voltage between 100 and 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. 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 Safety, regulatory and legal information  
8. Do not operate lamps beyond the rated lamp life. Excessive operation of lamps beyond the rated 
life could cause them to explode 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. This product is capable of displaying inverted images for ceiling mount installation. Please use 
BenQ’s Ceiling Mounting Kit for mounting the projector and ensure it is securely installed. 
12. Do not block the ventilation holes. 
- Do not place the projector on a blanket, bedding or any other soft surface. 
- Do not cover the 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 cause damage to 
the lamp, the projector to fail or result in  fire.
13. Do not place the 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 lifespan and darkening the screen. 
- Locations near fire alarms
- Locations with an ambient temperature above 35°C / 95°F 
- Locations where altitude are higher than 10000 feet.
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 or other components.  
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 it.
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.
Moisture condensation
Never operate the projector immediately after moving it from a cold location to a hot location. When the 
projector is exposed to such a change in temperature, moisture may condense on the crucial internal parts. To 
prevent the projector from possible damage, do not use the projector for at least 2 hours after a sudden change in 
temperature.
Avoid using volatile liquids
Do not use volatile liquids, such as insecticide or some types of cleaner, near the projector. Do not leave rubber or 
plastic products touching the projector for a long time. They will leave marks on the finish. When cleaning, be 
sure to follow the cleaning product’s safety instructions.
Disposal
This product contains the following materials which are harmful to humans and the environment.
•   Lead, which is contained in solder. 
•   Mercury, which is used in the lamp.
