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. 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). 
5. 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 
ECO BLANK on the remote 
control.

Safety Instructions (Continued)
6. The lamp becomes extremely hot 
during operation. Allow the 
projector to cool for approximately 
45 minutes prior to removing the 
lamp assembly for replacement. 
7. 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. 
8. Never replace the lamp assembly or 
any electronic components unless 
the projector is unplugged. 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. 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. 
11. 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)
12. 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). 
13. 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.
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.

Safety Instructions (Continued)
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 the projector. 
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 supplys 
wall socket and call BenQ to have the 
projector serviced. 18. This product is capable of displaying 
inverted images for wall mount 
installation.
Use only BenQs Wall Mount Kit for 
mounting the projector and ensure it is 
securely installed. 
Wall 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 wall, we strongly recommend 
that you use a proper fitting BenQ 
projector wall mount kit and that you 
ensure it is securely and safely 
installed.
If you use a non-BenQ brand 
projector wall mount kit, there is a 
safety risk that the projector may fall 
from the wall due to an improper 
attachment through the use of the 
wrong gauge or length screws.
You can purchase a BenQ projector 
wall 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 wall 
mount bracket. This will perform the 
secondary role of restraining the 
projector should its attachment to the 
mounting bracket become loose.
Hg - Lamp contains mercury. Manage in 
accordance with local disposal laws. See
