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

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.

The laser pointer is not a toy. Parents should be
mindful of the dangers of laser energy and keep
this remote control out of the reach of children.

Introduction 13
Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the back of the projector.
The remote control must be held at an angle within 30 degrees perpendicular to the
projector's IR remote control sensors to function correctly. The distance between the remote
control and the sensors should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensors on the
projector that might obstruct the infra-red beam.
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.
• Operating the projector from the front
Approx.+15º
• Operating the projector from the rear
Approx.+15º

Positioning your projector14
Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations:
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.
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 Position 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 Position 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 Position menu after you turn
the projector on.

Positioning your projector 15
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format
each factors in the projected image size.
Projection dimensions
Refer to "Dimensions" on page 71 for the center of lens dimensions of this projector before
calculating the appropriate position.
For example, if you are using a 120-inch screen, the recommended projection distance is
4457 mm and the vertical offset is 91 mm - 274 mm.
If your measured projection distance is 5.0 m (5000 mm), the closest match in the "Distance
from screen (mm)" column is 4457 mm or 5571 mm. Looking across this row shows that a
120'' (about 3.0 m) or 150'' (about 3.8 m) screen is required.
There is 3% 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 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.

Positioning your projector16
Shifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the projector
to be positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image height or width. It is
measured as an offset from the projected image’s vertical or horizontal center. You can use a
screwdriver to shift the projection lens within the allowable range depending on your
desired image position.
To shift the projection lens, open the flap on the side of the projector to expose an access (a
deep hole) to the lens shift device. Insert a screwdriver to touch the device, and then rotate
the screwdriver clockwise or counterclockwise until the screen is positioned where you want
it.
• To avoid causing damage to the lens shift device, rotate the screw driver slowly and
gently.
• Lens shift adjustment will not result in a degraded picture quality. In the unlikely event that
the image distortion is produced, see "Correcting keystone" on page 23 for details.

• Many notebooks do not turn on their external video ports when connected to a projector.
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate
a function key labeled CRT/LCD or a function key with a monitor symbol on the notebook.
Press FN and the labeled function key simultaneously. Refer to your notebook's
documentation to find your notebook's key combination.
• The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER
1 jack.
• If you wish to use this connection method when the projector is in standby mode, make
sure the Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See
"Standby Settings" on page 60 for details.
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 two built-in mono speakers 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 speakers.
The built-in speakers will be muted when the AUDIO OUT jack is connected.
• In the unlikely event that you connect the projector to a DVD player via the projector’s
HDMI input and the projected picture displays wrong colors, please change the color
space to YUV. See "Changing Color Space" on page 28 for details.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is
connected. See "Connecting audio" on page 18 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.

Connection 19
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.
You can also use a microphone to output the sound through the projector speaker.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)
menus. See "Audio Settings" on page 59 for details.
The table below describes the connection methods for different devices, and where the
sound is from.
About the microphone input
• If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the
projector.
• You can use a wireless microphone as long as a wireless module is attached to the
projector’s microphone input jack and it works well with the associated devices. To
ensure a quality use of the wireless microphone, it is recommended that your
microphone conforms to the specifications listed in the table below.
• There are two ways to adjust microphone volumes.
• Directly set microphone volume levels in the SYSTEM SETUP: Advanced >
Audio Settings > Microphone Volume menu or press MIC/VOL keys (+/-) on
the remote control.
• Set projector volume levels in the SYSTEM SETUP: Advanced > Audio Settings
> Volume menu, or press VOLUME+/VOLUME- on the remote control. (The
projector volume setting will affect the microphone volume.)
• To make the microphone input available when the projector is in standby mode, turn on
the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.
• If the microphone is not working, check the volume setting and cable connection.

• You might get feedback noise from the microphone when you are too close to the
speaker of the projector. Move the microphone away from the speaker of the projector.
The greater volume you require, the greater distance you need to be away from the
speaker to prevent the noise.
