							Introduction 12
Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and back 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 battery
1. Pull out the battery holder.
Please follow the illustrated instructions. Push and hold 
the locking arm while pulling out the battery holder.
2. Insert the new battery in the holder. Note the 
positive polarity should face outward.
3. Push the holder into the remote control.
•  Avoid excessive heat and humidity.
•  There may be battery damage if the battery is 
incorrectly replaced.
•  Replace only with the same or equivalent type 
recommended by the battery manufacturer.
•  Dispose of the used battery according to the battery 
manufacturers instructions.
•  Never throw a battery into a fire. There may be danger of an explosion.
•  If the battery is dead or if you will not be using the remote control for a long time, remove 
the battery to prevent 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.

							Positioning your projector 14
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.
For example, if you are using a 120-inch, 4:3-aspect-ratio screen and the projected picture is 
16:10, please refer to Table B2
 on page 16, the recommended projection distance is 1192 mm 
and the vertical offset is 76 mm.
If you need a 16:9 screen to project a 16:9 picture and your measured projection distance is 
1.5 m (1500 mm), please refer to Table A1
 on page 14. The closest match in the (b) Distance 
from screen column is 1623 mm. Looking across this row shows that a 150 (about 3.8 m) 
screen is required.
Projection dimensions 
Refer to Dimensions on page 59 for the center of lens dimensions of this projector before 
calculating the appropriate position.

sure the Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See 
Standby Settings on page 48 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 one built-in mono speaker which is designed to provide basic audio 
functionality accompanying data presentations for business purposes only. It is 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 speaker.
The built-in speaker 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 26 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.

signals. The current input signal being scanned 
displays in the upper left corner of the screen. If 
the projector doesnt detect a valid signal, the message “No Signal” will continue 
displaying until an input signal is found.
Yo u  c a n  a l s o  p r e s s  SOURCE on the projector or remote control to select your desired 
input signal. See Switching input signal on page 26 for details.
If the frequency/resolution of the input signal exceeds the projectors operating range, you will 
see the message “Out of Range” displayed on a blank screen. Please change to an input 
signal which is compatible with the projectors resolution or set the input signal to a lower 
setting. See Timing chart on page 62 for details. 
						

							Operation 20
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot. These 
adjusters change the image height and projection angle. To adjust the projector:
1. Press the quick-release button and lift the front 
of the projector. Once the image is positioned 
where you want it, release the quick-release 
button to lock the foot in position.
2. Screw the rear adjuster foot to fine-tune the 
horizontal angle.
To retract the foot, hold up the projector while 
pressing the quick-release button, then slowly lower 
the projector. Screw the rear adjuster foot in a reverse 
direction.
If the projector is not placed on a flat surface or the 
screen and the projector are not perpendicular to 
each other, the projected image becomes trapezoidal. 
To correct this situation, see Switching input signal 
on page 26 for details.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, press Auto on the 
projector or remote control. Within 3 seconds, the built-in Intelligent Auto Adjustment 
function will re-adjust the values of Frequency and Clock to provide the best picture quality. 
The current source information will be displayed in the corner of the screen for 3 seconds.
This function is only available when PC signal (analog RGB) is selected.
Fine-tuning the image clarity
Sharpen the image by rotating the focus ring.
