Important safety instructions 3

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. Always open the lens shutter

or remove the lens cap when

the projector lamp is on.

5. 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).

6. 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.

Important safety instructions4

Safety Instructions (Continued)

7. 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 operate lamps beyond the

rated lamp life. Excessive

operation of lamps beyond the

rated life could cause them to

break on rare occasions.

9. Never replace the lamp assembly

or any electronic components

unless the projector is unplugged.

10. Do not place this product on an

unstable cart, stand, or table. The

product may fall, sustaining

serious damage.

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.

12. 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.

Important safety instructions 5

Safety Instructions (Continued)

13. 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 3000 m (10000 feet).

14. 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.

15. 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 lamp.

Safety Instructions (Continued)

16. 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.

17. 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.

18. 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.

19. This product is capable of displaying

inverted images for ceiling mount

installation.

Use only BenQ's Ceiling

Mount Kit for mounting the

projector and ensure it is

securely installed.
