Operating the LASER pointer
The Laser Pointer is a 
presentation aid for 
professionals. It emits red 
colored 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. 
						

							Introduction 13
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 
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 73 for the center of lens dimensions of this projector before 
calculating the appropriate position.
•  MX713 ST/MX762 ST
For example, if you are using a 120-inch screen, the recommended projection distance is 
1481 mm and the vertical offset is 274 mm.
If your measured projection distance is 1.0 m (1000 mm), the closest match in the Distance 
from screen (mm) column is 988 mm. Looking across this row shows that a 80 (about 2.0 
m) screen is required.

							Positioning your projector 18Table C: The screen aspect ratio is 16:10 and the projected picture is 16:10
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 17, 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 16. 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.
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.

Connection
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 contents on page 8). They are commercially available from electronics stores.
•  The connection illustrations below are for reference only. The rear connecting jacks 
available on the projector vary with each projector model.

							Connection 20
•  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 simultaneously. 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 62 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 presentations 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 (MX762 ST only) on page 30 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 20 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.
