Important Safety Instructions 1
Important Safety Instructions
Your BenQ projector is designed and tested to meet the latest standards for safety of infor-
mation 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.
Caution
•To prevent shock, do not open the
cabinet. There are no user serviceable
parts inside.
•Please read this user’s manual before
you operate your projector. Save this
user’s manual for future reference.
•Do not look straight at the projector
lens during operation. The intense
light beam may damage your eyes.
•Refer servicing to qualified service
personnel.
•Always open the lens shutter or
remove the lens cap when the
projector lamp is on.
• 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).

Important Safety Instructions2
Safety Instructions
1. The lamp becomes extremely hot
during operation. Allow the projec-
tor to cool for approximately 45
minutes prior to removing the lamp
assembly for replacement.
2. Do not operate lamps beyond the
rated lamp life. Excessive operation
of lamps beyond the rated life could
cause them to break on rare occa-
sions.
3. Never replace the lamp assembly or
any electronic components unless
the projector is unplugged.
4. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.
5. To reduce the risk of electric shock,
do not disassemble this appliance.
Take it to a qualified technician
when service or repair is required.
Incorrect reassembly can cause mal-
function of the projector or electric
shock when the appliance is subse-
quently used.
6. This product is capable of displaying
inverted images for ceiling mount
installation. Please use BenQ’s Ceil-
ing Mounting Kit for mounting the
unit and ensure it is securely
installed.

Important Safety Instructions 3
Safety Instructions (Continued)
7. Do not block the ventilation holes.
- Do not place this unit on a blanket,
bedding or any other soft surface.
- Do not cover this unit with a cloth or any
other item.
- Do not place inflammables near the
projector.
If the ventilation holes are seriously
obstructed, overheating inside the unit
may result in a fire.
8. Do not place this unit in any of the fol-
lowing environments.
- Space where 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
- Locations with an ambient temperature
above 35°C / 95°F
9. Always place the unit on a level, hori-
zontal 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 unit when it is not fully
horizontal may cause a malfunction of, or
damage to, the lamp.
10. Do not stand the unit on end vertically.
Doing so may cause the unit to fall over,
causing injury or resulting in damage to
the unit.
11. Do not step on this unit or place any
objects upon it.
Besides probable physical damage to the
unit, doing so may result in accidents and
possible injury.
12. Do not place liquids near or on the pro-
jector. Liquids spilled into the projector
may cause it to fail. If the projector does
become wet, disconnect it from the
power supply’s wall socket and call
BenQ to have the projector serviced.

Introduction 9
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 of the projector’s IR remote
control sensors to function correctly. The distance between the remote control and the sen-
sors should not exceed 6 meters (19.5 feet).
Notes on Remote Control Operation:
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.
Installing or Replacing the Battery
1. Pull out the battery holder.
2. Insert the new battery in the
holder.
3. Push the holder into the
remote control.
Avoid excessive heat and humidity.
There may be danger of an explo-
sion if the battery is incorrectly
replaced. Replace only with the
same or equivalent type recom-
mended by the manufacturer. Dis-
pose of the used battery according
to the manufacturer’s instructions.
Blank In order to draw the audience’s full attention to the presenter, you
can use Blank to hide the screen image. Press Blank again to
restore the image. Refer to page 20 for more information.
Preset According to the selected input signal, there are several picture
setup options available: Vivid mode, Presentation mode, Gaming
mode, Video mode, Cinema mode and Economic mode. Refer to
page 23 for more information.

Installation 13
Installation
Choosing a Location
Your projector is designed to be installed in the four installation configurations shown here:
Floor front, Ceiling front, Floor rear, Ceiling rear. Your room layout or personal preference
will dictate which installation configuration you use.
For further information on the four configurations, please refer to page 26.
If you place the projector above or below the screen, you have to tilt it down or up to center
the image on the screen, in these situations image distortion will occur. Use the Keystone
function to correct the distortion. See page 18 for keystone correction.

III. Floor rear IV. Ceiling rear

Installation14
Adjusting the Height
The projector is equipped with 1 quick-release adjuster foot and 2 rear adjuster feet. These
adjusters change the image height and projection angle. To adjust the projector,
1. Lift the projector up and press
the adjuster button to release the
adjuster. The adjuster will drop
into position and be locked. It
can lift the projector by up to 15
degrees.
2. Screw the rear adjuster feet to
fine tune the horizontal angle.
Press the adjuster button again to
retract the foot.
If the screen and the projector are not perpendicular to each other, the projected image
becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the
Picture menu, on the projector control panel or on the remote control.
Screen Size
Place the projector at the required distance from the screen according to the required picture
size (see the table on the next page).

Operation16
Operation
Start Up
1. Switch all of the connected equipment on.
2. Plug the power cord into the projector and into a wall socket.
3. Turn on the wall socket switch (where fitted).
4. Press and hold Power on the remote control or projector to start the unit. The Power
indicator light flashes green and stays green when the power is turned on.
5. The start up procedure takes about 30 seconds after pressing Power. In the later stage
of start up, a default BenQ logo appears.
6. Then, the projector starts to search for input signals. Irrespective of selected input
source, the screen shows “Acquiring Signal” at the bottom right corner of the
screen. If there is no input source detected, one of three messages will be displayed on
the screen continuously: “Analog RGB Searching”, “ Video Searching”, “ S-Video
Searching”.
7. You can also press Source on the projector or remote control to select an input signal
to display if there are 2 or more devices are connected to the projector. For more infor-
mation, please refer to page 19.
If the frequency/ resolution of the input signal exceeds the projector’s operating range, you
will see the message “Out of Range” displayed on a blank screen.
