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. 
Caution
•To prevent shock, do not open the 
cabinet. There are no user serviceable 
parts inside. 
•Please read this user’s manual before 
you operate your projector. Save this 
user’s manual for future reference.   
•Do not look straight at the projector 
lens during operation. The intense 
light beam may damage your eyes. •Refer servicing to qualified service 
personnel. 
•Always open the lens shutter or 
remove the lens cap when the 
projector lamp is on. 
• 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).

of lamps beyond the rated life could 
cause them to break on rare 
occasions. 
3. Never replace the lamp assembly or 
any electronic components unless 
the projector is unplugged. 4. Do not place this product on an 
unstable cart, stand, or table. The 
product may fall, sustaining serious 
damage. 
5. To reduce the risk of electric shock, 
do not disassemble this appliance.

Safety Instructions (Continued)
6. 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 
projector’s 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 10000 feet.
7. Do not block the ventilation holes. 
- Do not place this unit on a blanket, 
bedding or any other soft surface. 
- Do not cover this unit with a cloth or any 
other item. 
- Do not place inflammables near the 
projector.   
If the ventilation holes are seriously 
obstructed, overheating inside the unit 
may result in a fire.
8. Always place the unit 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 unit when it is not fully 
horizontal may cause a malfunction of, or 
damage to, the lamp. 
9. Do not stand the unit on end vertically. 
Doing so may cause the unit to fall over, 
causing injury or resulting in damage to 
the unit.

10. 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.

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.
12. 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.13. This product is capable of displaying 
inverted images for ceiling mount 
installation. 
Please use BenQ’s Ceiling Mount Kit 
for mounting the unit and ensure it is 
securely installed. 
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.
