							Important safety instructions 5
1. Important safety instructions
Your BenQ 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. 
						

							6 Important safety instructions
  
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 
picture.
- Locations near fire alarms
- Locations with an ambient temperature 
above 35°C / 95°F
- Locations where the altitudes are higher 
than 1500 m / 4920 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 40 degrees left to right, nor at angle 
of more than 35 degrees front to back. 
Using the projector when it is not fully 
horizontal may cause a malfunction of, 
or damage to, the lamp.
1500 
meter 
/ 4920 
feet

Safety Instructions (Continued)
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.
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 pictures 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 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.
