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 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 the 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 closed.
- 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 35°C/95°F.

Important safety instructions
5. Do not block the vents while the projector is on
(even in standby mode).
- Do not cover the projector with any item.
- Do not place the projector on a blanket,
bedding or any other soft surface.
9. Do not look straight into the projector lens
during operation. It may harm your sight.
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.
10. Do not operate the projector lamp beyond the
rated lamp life. Excessive operation of lamps
beyond the rated life could cause a lamp to break
on rare occasions.
7. Do not step on the projector or place any objects
upon it.
11. 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 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 outlet and contact
BenQ to have the projector repaired.
12. Never attempt to replace the lamp assembly until
the projector has cooled down and is unplugged
from the power supply.

Important safety instructions
13. This projector is capable of displaying inverted
images for ceiling mount installation. Use only
BenQ's Ceiling Mount Kit for mounting.
Ceiling mounting the projector
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 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.
14. 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. See page 50.
Under no circumstances should you ever undo or
remove any other covers. Refer servicing only to
suitably qualified professional service personnel.
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.
15. 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.
Disposal
This product contains the following materials
which are harmful to human bodies and
environment.
Lead, which is contained in solder.
Mercury, which is used in the lamp.
To dispose of the product or used lamps, consult
your local environment authorities for regulations.
