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 of 19 volts DC, 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.

6. Never replace any electronic
components unless the projector is
unplugged.
7. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.
8. 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. Refer
servicing only to suitably qualified
professional service personnel.
9. 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.
10. 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.

Safety Instructions (Continued)
- 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).
11. 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.
12. Always place the projector on a level,
horizontal surface during operation.
13. 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.
14. 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.
15. 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.
