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).

Important safety instructions4

Safety Instructions

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 lamp, press

BLANK on the projector or remote

control.

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.

Important safety instructions 5

Safety Instructions (Continued)

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.

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.

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.

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.

*Gray areas mean it more than the lens ensureing distance, only for reference.

There is 5% tolerance among these numbers due to optical component variations. BenQ

recommends that if you intend to permanently install the projector, you should physically test

the projection size and distance using the actual projector before you permanently install it, so

as to make allowance for this projector's optical characteristics. This will help you determine

the exact mounting position so that it best suits your installation location.
