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.
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).
2.
Do not look straight at the
projector lens during operation.
The intense light beam may damage
your eyes.
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.
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.

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.
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.
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.
Under no circumstances should you
ever undo or remove any other
covers. Refer servicing only to
suitably qualified professional service
personnel.
9.
Never replace the lamp assembly or
any electronic components unless the
projector is unplugged.
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.

any objects upon it. Besides probable
physical damage to the projector, doing
so may result in accidents and possible
injury.
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.
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.
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.
19. This product is capable of displaying
inverted images for ceiling mount
installation.
Hg - Lamp contains mercury. Manage in
accordance with local disposal laws. See
Use only BenQ's Ceiling Mount Kit for
mounting the projector and ensure it is
securely installed.
20. This apparatus must be earthed.

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.

Connecting video source devices
You need only connect the projector to a video source device using just one of the
connecting methods, however each provides a different level of video quality. The method
you choose will most likely depend upon the availability of matching terminals on both the
projector and the video source device as described below:

Connecting audio
The projector has built-in mono speaker(s) 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(s).
The built-in speaker(s) 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 17 for details.
•
If the selected video image is not displayed after the projector is turned on and the correct video source
has been selected, check that the video source device is turned on and operating correctly. Also check
that the signal cables have been connected correctly.
Playing sound through the projector
You can make use of the projector (mixed mono) speaker(s) 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.
You can also use a microphone to output the sound through the projector speaker(s).
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)

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.

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:
