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. The only

user serviceable part is the lamp

which has its own removable cover.

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.

Important safety instructions6

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.
