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. 
						

							Introduction 13
Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the top of the projector. 
The remote control must be held at an angle within 30 degrees perpendicular to the 
projectors 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 manufacturers 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.

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 75 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 projectors optical characteristics. This 
will help you determine the exact mounting position so that it best suits your installation 
location.

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 simu ltaneously. Refer to your notebooks 
documentation to find your notebooks 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 64  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 presentation s 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.

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 63 for details.
The table below describes the connection methods for different devices, and where the 
sound is from.
The projector can play sound if the connected RJ45 cable or USB cable carries audio signal. 
There is no need to connect the audio cable when the USB Display or Network Display source 
is selected.
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. 
•Press MIC/VOL keys (+/-) on the remote control.
•  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.

The selected input signal determines which sound will be played by the projector speaker, 
and which sound will be output from the projector when AUDIO OUT is connected. If you 
select the COMPUTER 1/YPbPr 1 signal, the projector can play the sound received from 
AUDIO IN 1/MIC. If you select the COMPUTER 2/YPbPr 2 signal, the projector can play the 
sound received from AUDIO IN 2/MIC.

							Connection 20•  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.
