							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.
BlankIn 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.
PresetAccording 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.

Connecting Equipment to the Component Video
Input
The projector is capable of displaying various High Definition TV display modes. Some of 
these sources are:  
Most of these sources will provide an analog component video output, a standard VGA out-
put, or a YP
bPr (default) format. 
The projector is capable of accepting HDTV data through a Component Video connector. 
Use a Component Video cable (optional accessory) to display these images.
The following standards are supported in the HDTV function:     
Connecting Video and S-Video Devices

							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 tile 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 rearIV. Ceiling rear 
						

							Installation 14
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).

							Operation 16
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.
