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. 
Safety Instructions
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 or 
remove the lens cap when the 
projector lamp is on. 
5. 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). 
6. 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, press 
BLANK on the projector or remote 
control. 
						

							Important safety instructions 4  
Safety Instructions (Continued)
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. 
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. 
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. 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.

Safety Instructions (Continued)
13. 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, shortening the 
projectors life span and darkening 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).
14. 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.
15. 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. 
16. 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.

Safety Instructions (Continued)
17. 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.
18. 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 supplys wall socket 
and call BenQ to have the projector 
serviced.
19. This product is capable of displaying 
inverted images for ceiling mount 
installation. 
Use only BenQs Ceiling Mount Kit for 
mounting the projector and ensure it is 
securely installed. 
Ceiling mounting the projector
We want you to have a pleasant 
experience using your BenQ projector, 
so we need to bring this safety matter to 
your attention to prevent possible 
damage to person and property.
If you intend to mount your projector 
on the ceiling, we strongly recommend 
that you use a proper fitting BenQ 
projector ceiling mount kit and that 
you ensure it is securely and safely 
installed.
If you use a non-BenQ brand projector 
ceiling mount kit, there is a safety risk 
that the projector may fall from the 
ceiling due to an improper attachment 
through the use of the wrong gauge or 
length screws.
You can purchase a BenQ projector 
ceiling mount kit from the place you 
purchased your BenQ projector. BenQ 
recommends that you also purchase a 
separate Kensington lock compatible 
security cable and attach it securely to 
both the Kensington lock slot on the 
projector and the base of the ceiling 
mount bracket. This will perform the 
secondary role of restraining the 
projector should its attachment to the 
mounting bracket become loose.
