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 (if

any) or remove the lens cap (if

any) when the projector light

source 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. To

temporarily turn off the light source,

press ECO BLANK on the

projector or remote control.

Important safety instructions4

Safety Instructions (Continued)

7. Do not operate light sources beyond

the rated light source life. Excessive

operation of light sources beyond the

rated life could cause them to fail on

rare occasions.

8. Do not place this product on an

unstable cart, stand, or table. The

product may fall, sustaining serious

damage.

9. 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 cover. Refer

servicing only to suitably qualified

professional service personnel.

10. 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.

11. 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).

Safety Instructions (Continued)

12. 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.

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. 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.

16. 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.

17. This apparatus must be earthed.

Important safety instructions6

Safety Instructions (Continued)

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. Also, maintain a minimum distance of 15

mm between the vent on the bottom of the projector and the mounting plate. This is

crucial for proper air circulation and cooling of the unit.

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.
