4 Important safety instructions
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.
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 (if any) or
remove the lens cap (if any) when the
projector light source is on.
5. The light source becomes extremely hot
during operation.
6. 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).
7. 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
light source, use the blank function.
8. Do not operate light sources beyond the
rated light source life.
5Important safety instructions
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.
Under no circumstances should you ever
undo or remove any other covers. Refer
servicing only to suitably qualified
professional service personnel.
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.
- 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 light source.
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. 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.
6 Important safety instructions
16. 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 power outlet and call BenQ to
have the projector serviced.
17. This product is capable of displaying
inverted images for ceiling/wall mount
installation.
18. This apparatus must be earthed.
19. 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 life span and
darken 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).
Risk Group 2
1. According to the classification of photobiological safety of light sources and light source
systems, this product is Risk Group 2, IEC 62471-5:2015.
2. Possibly hazardous optical radiation emitted from this product.
3. Do not stare at operating light source. May be harmful to the eyes.
4. As with any bright source, do not stare into the direct beam.
To avoid damaging the DLP chips, never aim a high-power laser beam into the projection lens.
