6. 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).
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 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.
11. 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.
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.
12. 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.

Important safety instructions
13. 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.
14. 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.
15. 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.
16. 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.
17. 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
BLANK on the projector or remote control.
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 wall

serviced.
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.

light when you press it and the indicator
lights up red.
The laser beam is visible. It is necessary to
press and hold LASER for continuous
output.
Do not look into the laser light
window or shine the laser light beam on
yourself or others. See the warning messages
on the back of the remote control prior to
using it.
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.
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.

Making the remote control a wired control
The remote control is equipped with a jack on the top
allowing connection to the projector with a 2.5mm
mini jack cable available in the market. This helps you
easily locate the remote control when needed as it is
connected to the projector and within the distance no
greater than the cable’s length.
Introduction

Positioning your projector
Choosing a location
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.
Your projector is designed to be installed in one of four possible installation locations:
1. Front Table
Select this location with the projector placed near the
floor in front of the screen. This is the most common
way to position the projector for quick setup and
portability.
3. Rear Table
Select this location with the projector placed near the
floor behind the screen.
Note that a special rear projection screen is required.
*Set Rear Table after you turn the projector on.
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 after you turn the projector on.
4. 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 after you turn the projector on.
*To set the projector position:
1. Press MENU/EXIT on the projector or remote control and then press /
until the SYSTEM SETUP: Basic menu is highlighted.
2. Press / to highlight Projector Position and press / until the
correct position is selected.

Positioning your projector
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.
4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9 (widescreen) aspect ratio
image, the projector can resize and scale a widescreen image to the projector's native aspect width. This will result
in a proportionally smaller height equivalent to 75% of the projector's native aspect height.
4:3 aspect image in a 4:3
aspect display area
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed by this projector. This
will be seen as darkened (unlit) bars along the top and bottom (vertical 12.5% height respectively) of the 4:3
projection display area whenever displaying a scaled 16:9 aspect image in the vertical center of the 4:3 projection
display area.
The projector should always be placed horizontally level (like flat on a table), and positioned directly
perpendicular (90° right-angle square) to the horizontal center of the screen. This prevents image distortion
caused by angled projections (or projecting onto angled surfaces).
The modern digital projector does not project directly forward (like older style reel-to-reel film projectors did).
Instead, digital projectors are designed to project at a slightly upward angle above the horizontal plane of the
projector. This is so that they can be readily placed on a table and will project forward and upwards onto a screen
positioned so that the bottom edge of the screen is above the level of the table (and everyone in the room can see
the screen).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects at a slightly
downward angle.
You can see from the diagram on page 15, that this type of projection causes the bottom edge of the projected
image to be vertically offset from the horizontal plane of the projector. When ceiling mounted, this refers to the
top edge of the projected image.
If the projector is positioned further away from the screen, the projected image size increases, and the vertical
offset also increases proportionately.
When determining the position of the screen and projector, you will need to account for both the projected
image size and the vertical offset dimension, which are directly proportional to the projection distance.
BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the ideal location for your
projector. There are two dimensions to consider, the perpendicular horizontal distance from the center of the
screen (projection distance), and the vertical offset height of the projector from the horizontal edge of the screen
(offset).

How to determine the position of the projector for a given screen size
1. Select your screen size.
2. Refer to the table and find the closest match to your screen size in the left columns labelled "4:3 screen
diagonal". Using this value, look across this row to the right to find the corresponding average distance
from screen value in the column labelled "Average". This is the projection distance.
3. On that same row, look across to the right column and make note of the "Vertical offset in mm" value. This
will determine the final vertical offset placement of the projector in relation to the edge of the screen.
4. The recommended position for the projector is aligned perpendicular to the horizontal center of the screen,
at the distance from the screen determined in step 2 above, and offset by the value determined in step 3
above.
For example, if you are using a 120-inch screen, the average projection distance is 4416 mm and with a vertical
offset of 210 mm.
If you place the projector in a different position (to that recommended), you will have to tilt it down or up to
center the image on the screen. In these situations, some image distortion will occur. Use the Keystone function
to correct the distortion. See "Correcting keystone" on page 28 for details.
How to determine the recommended screen size for a given distance
This method can be used for situations where you have purchased this projector and would like to know what
screen size will fit in your room.
The maximum screen size is limited by the physical space available in your room.
1. Measure the distance between the projector and where you want to position the screen. This is the
projection distance.
2. Refer to the table and find the closest match to your measurement in the average distance from screen
column labelled "Average". Check that your measured distance is between the min and max distances listed
on either side of the average distance value.
3. Using this value, look across that row to the left to find the corresponding screen diagonal listed in that row.
That is the projected image size of the projector at that projection distance.
4. On that same row, look across to the right column and make note of the "Vertical offset in mm" value. This
will determine the final placement of the screen in relation to the horizontal plane of the projector.
For example, if your measured projection distance was 4.5 m (4500 mm), the closest match in the "Average"
column is 4416 mm. Looking across this row shows that a 120-inch screen is required. If you can only obtain
metric sized screens, the listed screen sizes on either side of the 120-inch screen are the 3.0 m (3000 mm) and 3.5
m (3500 mm) screens.
Checking the min and max projection distance values for these screen sizes, indicates that the 4.5 m measured
projection distance will also fit the 3.0 m (3000 mm) size screen. Be aware that these different screens have
different vertical offset values.
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.

When connecting a signal source to the projector, be sure to:
1. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Ensure the cables are firmly inserted.
In the connections shown below, some cables may not be included with the projector (see "Shipping

Connecting a computer
The projector provides a VGA input socket that allows you to connect it to both IBM® compatibles and
Macintosh® computers. A Mac adapter (an optional accessory) is needed if you are connecting legacy version
Macintosh computers.
Additionally, you can also connect the projector to a computer via the USB cable so you can perform paging
operations of the application on the PC or notebook.
To connect the projector to a notebook or desktop computer:
•With a VGA cable: •With a DVI-D cable:
Your computer must be equipped with a
DVI-D input socket.
1. Take the supplied VGA cable and connect one end
to the D-Sub output socket of the computer.
Connect the other end of the VGA cable to the DSUB/COMP. IN signal input socket on the
projector.
2. If you wish to use the remote paging function, take a USB cable and connect the larger end to the USB port
of the computer, and the smaller end to the (USB) socket on the projector. See "Remote paging
operations" on page 34 for details.
3. If you wish to make use of the projector (mixed mono) speakers in your presentations, take a suitable audio
cable and connect one end of the cable to the audio output socket of the computer, and the other end to the
AUDIO socket of the projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See
"Audio Settings" on page 42 for details.
