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 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. To

temporarily turn off the lamp, press

ECO BLANK on the projector or

remote control.

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,

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).

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.

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.

Important safety instructions6

Safety Instructions (Continued)

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

power outlet 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.

20. 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. See

providing a true 1:1 image reproduction.

• SmartEco™ starts your dynamic power saving

The SmartEco™ technology offers a new way of operating the projector lamp system

and saves lamp power depending on the content brightness level.

• Longest lamp life with SmartEco™ technology

The SmartEco™ technology lowers the power consumption and increases the lamp

life.

• ECO BLANK saves the lamp power

Pressing the ECO BLANK button to hide the image and immediately lower the lamp

power at the same time.

• Less than 0.5W in standby condition

Less than 0.5W power consumption under standby mode.

• Presenting from a USB Reader

This feature displays a slide show of images stored on a USB flash drive connected to

the projector. It can eliminate the need for a computer source.

• USB Display

This feature allows the projector to display contents from your computer by using a

single USB cable and without the need for any driver.

• Presenting from your mobile devices by Wireless Display

This feature allows a PC-free presentation with the help of an optional wireless dongle

and the BenQ Qpresenter App. By selecting source Network Display in the OSD

menu, you can start your presentation with your mobile devices without any wired

connection!

• Quick Cooling, Auto Power Off, Signal Power On, Direct Power On

Quick Cooling function speeds up the cooling process when turning off the

projector. Auto Power Off function allows the projector to turn off automatically if

no input signal is detected after a set period of time. Signal Power On function turns

on your projector automatically once detecting the signal input and Direct Power

On boots up the projector automatically when the power is connected.

• Instant Restart

Selectable Instant Restart function enables you to restart the projector immediately

within 90 seconds after turning it off.

• 3D Function supported

Various 3D formats make the 3D function more flexible. By presenting the depth of the

images, you can wear BenQ 3D glasses to enjoy the 3D movies, videos and sporting

events in a more realistic way.

• The apparent brightness of the projected image will vary depending on the ambient lighting conditions,

selected input signal contrast/brightness settings, and is directly proportional to projection distance.

• The lamp brightness will decline over time and may vary within the lamp manufacturers specifications. This

is normal and expected behavior.
