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. 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).

5. Do not block the projection lens with

any objects as this could cause the

objects to become heated and

deformed or even cause a fire. To

temporarily turn off the lamp, press

ECO BLANK on the projector or

remote control.

Important safety instructions4

Safety Instructions (Continued)

6. The lamp becomes extremely hot

during operation. Allow the projector

to cool for approximately 45 minutes

prior to removing the lamp assembly

for replacement.

7. 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.

8. Never replace the lamp assembly or

any electronic components unless the

projector is unplugged.

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. 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.

11. 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)

12. 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).

13. 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.

14. 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.

15. 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.

Important safety instructions6

Safety Instructions (Continued)

16. 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.

17. 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.

18. 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.

19. This apparatus must be earthed.

Ceiling mounting the projector

We want you to have a pleasant

experience using your BenQ projector,

so we need to bring this safety matter to

your attention to prevent possible

damage to person and property.

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 that

you 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.

Hg - Lamp contains mercury. Manage in

accordance with local disposal laws.
