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.

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).

lamp, press ECO BLANK on
the remote control.

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

Safety Instructions (Continued)

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.

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,
shortening the projector's life span
and darkening the image.

- Locations near fire alarms

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.

installed.

Wall 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 wall, we
strongly recommend that you
use a proper fitting BenQ
projector wall mount kit and
that you ensure it is securely and
safely installed.
If you use a non-BenQ brand
projector wall mount kit, there
is a safety risk that the projector
may fall from the wall due to an
improper attachment through
the use of the wrong gauge or
length screws.

Important safety instructions 7

Safety Instructions (Continued)

You can purchase a BenQ
projector wall 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

wall mount bracket. This will
perform the secondary role of
restraining the projector should
its attachment to the mounting
bracket become loose.

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.

It is recommended to adjust focus 15 minutes after powering on due to the
slight shifting of the lens from temperature changing.

of matching terminals on both the projector and the video source device as
described below:

Te r m ina l n ame Terminal appearance Picture quality

HDMI Best

Component Video Better

S-Video Good

Video Normal

Connecting audio

The projector has one built-in mono speaker which are designed to provide
basic audio functionality accompanying data presentations for business
purposes only. They are not designed for, nor intended for stereo audio
reproduction use as might be expected in home theater or home cinema
applications. Any stereo audio input (if provided), is mixed into a common
mono audio output through the projector speaker.

The built-in speaker will be muted when the AUDIO OUT jack is
connected.

• The projector is only capable of playing mixed mono audio, even if a
stereo audio input is connected. See "Connecting audio" on page 26 for
details.

Playing sound through the projector

You can make use of the projector (mixed mono) speaker in your
presentations, and also connect separate amplified speakers to the AUDIO
OUT socket of the projector.

If you have a separate sound system, you will most likely want to connect the
audio output of your Video source device to that sound system, instead of to
the mono audio projector.

Once connected, the audio can be controlled by the projector On-Screen
Display (OSD) menus.

The table below describes the connection methods for different devices, and
where the sound is from.

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.

Operation40

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.

1. Cooler: makes the image appear bluish white.

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 and the 3D Color Management page displays.

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

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.

Please refer to the illustration to the
right for how the colors relate to each
other.

For example, if you select Red and set
its range at 0, only pure red in the
projected picture will be selected.
Increasing its range will include red
close to yellow and red close to
magenta.

5. Press ▼ to highlight Saturation and
adjust its values to your preference by
pressing ◄/►. Every adjustment made will reflect to the image
immediately.

Operation42

For example, if you select Red and set its value at 0, only the saturation
of pure red will be affected.

Saturation is the amount of that color in a video picture. Lower settings
produce less saturated colors; a setting of “0” removes that color from the
image entirely. If the saturation is too high, that color will be overpowering
and unrealistic.

6. Press ▼ to highlight Gain and adjust its values to your preference by
pressing ◄/►. The contrast level of the primary color you select will be
affected. Every adjustment made will reflect to the image immediately.

7. Repeat steps 3 to 6 for other color adjustments.

8. Make sure you have made all of the desired adjustments.

9. Press MENU/EXIT to exit and save the settings.

Operating in a high altitude environment

We recommend you use the High Altitude Mode when your environment
is between
1500 m –3000 m above sea level, and temperature is between 0°C–30°C.

Do not use the High Altitude Mode if your altitude is between 0 m and
1500 m and temperature is between 0°C and 35°C. The projector will be
over cooled, if you turn the mode on under such a condition.

To activate the High Altitude Mode:

1. Press MENU/EXIT and then press ◄/► until the System Setup:
Advanced menu is highlighted.

2. Press ▼ to highlight High Altitude Mode and press ◄/► to select
On. A confirmation message displays.

3. Highlight Yes and press MODE/ENTER.

Operation under "High Altitude Mode" may cause a higher decibel
operating noise level because of increased fan speed necessary to improve
overall system cooling and performance.

If you use this projector under other extreme conditions excluding the
above, it may display auto shut-down symptoms, which is designed to protect
your projector from over-heating. In cases like this, you should switch to
High Altitude mode to solve these symptoms. However, this is not to state
that this projector can operate under any and all harsh or extreme
conditions.

Maintenance

Care of the projector

Your projector needs little maintenance. The only thing you need to do on a
regular basis is to keep the lens clean.

Never remove any parts of the projector except the lamp. Contact your
dealer if other parts need replacing.

Cleaning the Projector Mirror

Remove the dust with a "Bellows/Lens Blower" readily available from camera
shops to prevent scratching the mirror with subsequently wiped.

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.

• Use a canister of compressed air to remove dust.

• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth
with lens cleaner and gently wipe the lens surface.

Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or
volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such
materials or maintaining prolonged contact with rubber or vinyl materials
may result in damage to the projector surface and cabinet material.

Cleaning the projector case

Before you clean the case, turn the projector off using the proper shutdown
procedure as described in "Shutting down the projector" on page 50 and
unplug the power cord.

• To remove dirt or dust, wipe the case with a soft, lint-free cloth.

Lamp information

Getting to know the lamp hour

When the projector is in operation, the duration (in hours) of lamp usage is
automatically calculated by the built-in timer. The method of calculating the
equivalent lamp hour is as follows:

See "Setting Lamp mode as Economic or SmartEco" below for more
information on Economic mode.

To obtain the lamp hour information:

The projection lamp is a consumable item. To keep the lamp life as long as
possible, you can do the following settings via the OSD menu.

Setting Lamp mode as Economic or SmartEco

Using Economic mode reduces system noise and power consumption by
15%. Using SmartEco mode reduces system noise and lamp power
consumption by up to 30%. If the Economic or SmartEco mode is
selected, the light output will be reduced and result in darker projected
pictures.

Setting the projector in Economic or SmartEco mode also extends the
lamp operation life. To set Economic or SmartEco mode, go into the
SYSTEM SETUP: Advanced > Lamp Settings > Lamp mode menu

and press ◄/► until your desired mode is selected.

When the Lamp indicator lights up red or a message appears suggesting it
is time to replace the lamp, please install a new lamp or consult your dealer.
An old lamp may cause a malfunction in the projector and in some instances
the lamp may explode.

Total (equivalent) lamp hour = 1.75*(hours used in Normal mode) +

1.40*(hours used in Economic mode) + 1.00*(hours used in SmartEco mode)

Go to http://www.benq.com for a replacement lamp.

The Lamp indicator light and Temperature warning light will light up if the
lamp becomes too hot. Turn the projector off and let the projector cool for
45 minutes. If the lamp or Temp indicator still lights up after turning the
power back on, please contact your dealer. See "Indicators" on page 73 for

Replacing the lamp

• 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.

• 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 BenQ projector lamp for lamp replacement.

• 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 wall socket. If

the lamp is hot, avoid burns by waiting for approximately 45 minutes
until the lamp has cooled.

2. Loosen the screw from the right

side.

3. Remove the lamp compartment

cover as shown.

Maintenance 69

4. Loosen the two captive screws

that secure the lamp.

• 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.

5. Lift the handle so that it stands

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

6. Insert the new lamp into the

lamp compartment and make
sure it fits in the projector.

• Ensure the connectors are aligned.

• If you experience resistance, lift
the lamp and start again.

Maintenance70

7. Tighten the screws that secure

the lamp.

8. 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.

9. Replace the lamp compartment

cover on the projector and
tighten the screw.

10. Restart the projector.

Do not turn the power on with the lamp cover removed.

Resetting the lamp timer

11. After the startup logo, open the On-Screen Display (OSD) menu. Go to

the SYSTEM SETUP: Advanced > Lamp Settings menu. Press

MODE/ENTER. The Lamp Settings page displays. Highlight Reset
lamp timer. A warning message displays asking if you want to reset the

lamp timer. Highlight Reset and press MODE/ENTER. The lamp time
will be reset to '0'.

Do not reset if the lamp is not new or replaced as this could cause damage.

Maintenance 71

Cleaning the projector mirror

Remove dust with a “Bellows/Lens Blower” readily available from Camera
shops to prevent scratching the mirror when subsequently wiped.

• Always turn the projector off and allow to cool for at least 30
minutesprior to cleaning.
