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 light
source 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

Important safety instructions6
Safety Instructions (Continued)
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. Also, maintain a minimum distance of 15
mm between the vent on the bottom of the projector and the mounting plate. This is
crucial for proper air circulation and cooling of the unit.
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.

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 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.

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
The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio
For example, if you are using a 120-inch screen, the recommended projection distance is
1481 mm and the vertical offset is 274 mm.
If your measured projection distance is 2.0 m (2000 mm), the closest match in the
"Distance from screen (mm)" column is 1852 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.

Connection 17
• 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 PC 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 43 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. See "Changing Color Space"
on page 25 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.
