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.
1. Please read this user manual before you operate your projector.
Keep this manual in a safe place for future reference.
2. Always place the projector on a level, horizontal surface during
operation.
• Do not place the projector on an unstable cart, stand, or table as it
may fall and be damaged.
• Do not place inflammables near the projector.
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.
3. Do not store the projector on end vertically. Doing so may cause the
projector to fall over, causing injury or resulting in damage.
4. 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, shorten the projector’s lifespan
and darken the screen.
• Locations near fire alarms.
• Locations with an ambient temperature above 40°C /104°F

5. Do not block the vents holes while the projector is on (even in power-
saving mode).
• Do not cover the projector with any item.
• Do not place the projector on a blanket, bedding or any other soft
surface.
6. In areas where the mains power supply voltage may fluctuate by
±10 volts, it is recommended that you connect the projector through
a power stabilizer, surge protector or uninterruptible power supply
(UPS) as appropriate to your situation.

9
7. Do not step on the projector or place any objects upon it.
8. Do not place liquids near or on the projector. Liquids spilled into
the projector will void your warranty. If the projector does become
wet, disconnect it from the power point and call BenQ to have the
projector repaired.
9. Do not look straight into the projector lens during operation. It may
harm your sight.
10. Do not operate the projector LED beyond the rated LED life.
Excessive operation of LEDs beyond the rated life could cause LEDs
to break on rare occasions.

10
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.
Under no circumstances should you ever undo or remove any other
covers. Refer servicing only to suitably qualified professional service
personnel.
Warning
• Please keep the original packing for possible future shipment.
• If you need to pack your projector after use, adjust the projection lens to an appropriate position,
put the lens cushion around the lens, and fit the lens cushion and projector cushion together to
prevent damage during transportation.
12. When you think service or repair is required, take the projector only
to a suitably qualified technician.
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 when there is a sudden change in temperature.
Avoid volatile liquids
Do not use volatile liquids, such as insecticide or certain types of cleaner,
near the projector. Do not have rubber or plastic products touching the
projector for a long time. They will leave marks on the finish. If cleaning
with a chemically treated cloth, be sure to follow the cleaning product’s
safety instructions.
