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.

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).

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.

4. Always open the lens shutter (if

any) or remove the lens cap (if
any) when the projector lamp is
on.

Important safety instructions 3

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.

10. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.

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.

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.

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 instructions 5

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.

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

Introduction14

Replacing the remote control batteries

1. To open the battery cover, turn the remote control over to view its back, push on
the finger grip on the cover and slide it up in the direction of the arrow as illustrated.
The cover will slide off.

2. Remove any existing batteries (if necessary) and install two AAA batteries observing
the battery polarities as indicated in the base of the battery compartment. Positive
(+) goes to positive and negative (-) goes to negative.

3. Refit the cover by aligning it with the base and sliding it back down into position. Stop
when it clicks into place.

• Avoid leaving the remote control and batteries in an excessive heat or humid environment like the

kitchen, bathroom, sauna, sunroom or in a closed car.

• Replace only with the same or equivalent type recommended by the battery manufacturer.

• Dispose of the used batteries according to the manufacturer's instructions and local environment

regulations for your region.

• Never throw the batteries into a fire. There may be danger of an explosion.

• If the batteries are dead or if you will not be using the remote control for an extended period of time,

remove the batteries to avoid damage to the remote control from possible battery leakage.

Introduction 15

Positioning your projector

Choosing a location

Your projector is designed to be installed in one of four possible installation locations:

1. Front Table

Select this location with the projector
placed on the table in front of the screen.
This is the most common way to position
the projector for quick setup and
portability.

2. Front Ceiling

Select this location with the projector
suspended upside-down from the ceiling in
front of the screen.

Purchase the BenQ Projector Ceiling
Mount Kit from your dealer to mount your
projector on the ceiling.

Set Front Ceiling in the SYSTEM
SETUP: Basic > Projector Installation
menu after you turn the projector on.

3. Rear Ceiling

Select this location with the projector
suspended upside-down from the ceiling
behind the screen.

Note that a special rear projection screen
and the BenQ Projector Ceiling Mount Kit
are required for this installation location.

Set Rear Ceiling in the SYSTEM
SETUP: Basic > Projector Installation
menu after you turn the projector on.

4. Rear Table

Select this location with the projector
placed on the table behind the screen.

Note that a special rear projection screen
is required.

Set Rear Table in the SYSTEM SETUP:
Basic > Projector Installation menu
after you turn the projector on.

Your room layout or personal preference will dictate which installation location you select.
Take into consideration the size and position of your screen, the location of a suitable
power outlet, as well as the location and distance between the projector and the rest of
your equipment.

For example, if you are using an 120-inch screen, the recommended projection distance is
3608 mm and the vertical offset is 162 mm.

If your measured projection distance is 4.5 m (4500 mm), the closest match in the

"Projection distance (mm)" column is 4510 mm. Looking across this row shows that a 150''

(about 3.8 m) screen is required.

All measurements are approximate and may vary from the actual sizes.
BenQ recommends that if you intend to permanently install the projector, you should physically test the
projection size and distance using the actual projector in situ 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.

Adjusting Contrast

The higher the value, the greater the contrast. Use this
to set the peak white level after you have previously
adjusted the Brightness setting to suit your selected
input and viewing environment.

Adjusting Color

Lower setting produces less saturated colors. If the setting is too high, colors on the image
will be overpowering, which makes the image unrealistic.

Adjusting Tint

The higher the value, the more reddish the picture becomes. The lower the value, the
more greenish the picture becomes.

Adjusting Sharpness

The higher the value, the sharper the picture becomes. The lower the value, the softer the
picture becomes.

Adjusting Brilliant Color

This feature utilizes a new color-processing algorithm and system level enhancements to
enable higher brightness while providing truer, more vibrant colors in picture. It enables a
greater than 50% brightness increase in mid-tone images, which are common in video and
natural scenes, so the projector reproduces images in realistic and true colors. If you
prefer images with that quality, select On. If you don’t need it, select Off.

When Off is selected, the Color Temperature function is not available.

Selecting a color temperature

The options available for color temperature* settings vary according to the signal type
selected.

2. Normal: Maintains normal colorings for white.

3. Warm: Makes images appear reddish white.

*About color temperatures:

There are many different shades that are considered to be "white" for various purposes.
One of the common methods of representing white color is known as the “color
temperature”. A white color with a low color temperature appears to be reddish white. A
white color with a high color temperature appears to have more blue in it.

3D Color Management

In most installation situations, color management will not be necessary, such as in
classroom, meeting room, or lounge room situations where lights remain on, or where
building external windows allow daylight into the room.

Only in permanent installations with controlled lighting levels such as boardrooms, lecture
theaters, or home theaters, should color management be considered. Color management
provides fine color control adjustment to allow for more accurate color reproduction,
should you require it.

Proper color management can only be achieved under controlled and reproducible viewing
conditions. You will need to use a colorimeter (color light meter), and provide a set of
suitable source images to measure color reproduction. These tools are not provided with
the projector, however, your projector supplier should be able to provide you with suitable
guidance, or even an experienced professional installer.

The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you
select each color, you can independently adjust its range and saturation according to your
preference.

If you have purchased a test disc which contains various color test patterns and can be
used to test the color presentation on monitors, TVs, projectors, etc, you can project any
image from the disc on the screen and enter the 3D Color Management menu to make
adjustments.

To adjust the settings:

1. Go to the PICTURE menu and highlight 3D Color Management.

2. Press MODE/ENTER on the projector or remote control and the 3D Color
Management page displays.

3. Highlight Primary Color and press / to select a color from among Red,
Yellow, Green, Cyan, Blue, or Magenta.

4. Press to highlight Hue and press / to select its range. Increase in the range
will include colors consisted of more proportions of its two adjacent colors.

• To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before
changing the lamp.

• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the
lamp.

• To reduce the risk of injuries to fingers and damage to internal components, use caution when removing
lamp glass that has shattered into sharp pieces.

• To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do not
touch the empty lamp compartment when the lamp is removed.

• This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a
proper manner.

• To assure optimal performance from the projector, it is recommended that you purchase a qualified
projector lamp for lamp replacement.

• If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make
sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes
caused by fractured lamp.

• Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety
glasses, goggles or face shield and wear protective clothing such as gloves.

1. Turn the power off and disconnect the projector from the power outlet. If the lamp
is hot, avoid burns by waiting for approximately 45 minutes until the lamp has
cooled.

2. Loosen the screw that secures the lamp
cover on the side of the projector until
the lamp cover loosens.

3. Remove the lamp cover from the
projector.

• Do not turn the power on with the lamp cover

removed.

• Do not insert your fingers between the lamp and the

projector. The sharp edges inside the projector may
cause injuries.

4. Loosen the screw that secures the lamp.

5. Lift the handle so that it stands up.

Maintenance56

6. Use the handle to slowly pull the lamp out of

1

the projector.

• Pulling it too quickly may cause the lamp to break and
scatter broken glass in the projector.

• Do not place the lamp in locations where water might
splash on it, children can reach it, or near flammable
materials.

• Do not insert your hands into the projector after the
lamp is removed. If you touch the optical components
inside, it could cause color unevenness and distortion of
the projected images.

7. As shown in the figure, lower the new lamp.

8. Tighten the screw that secures the lamp.

9. Ensure the handle is fully laid flat and locked

in place.

• Loose screw may cause a bad connection, which could
result in malfunction.

• Do not over tighten the screw.

10. Replace the lamp cover on the projector.

11. Tighten the screw that secures the lamp

cover.

• Loose screw may cause a bad connection, which could
result in malfunction.
