							Introduction 12
Remote control effective range
The remote control must be held at an angle within 30 degrees perpendicular to the 
projectors IR remote control sensor(s) to function correctly. The distance between the 
remote control and the sensor(s) should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensor(s) 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.
•  Operating the projector from the front

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 Installation 
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 Installation 
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 Installation menu 
after you turn the projector on.

							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.
Projection dimensions 
Refer to Dimensions on page 52 for the center of lens dimensions of this projector 
before calculating the appropriate position.
The screen aspect ratio is 4:3 and the projected picture is in a 4:3 aspect ratio
For example, if you are using an 120-inch screen, the recommended projection distance is 
4755 mm and the vertical offset is 183 mm.
If your measured projection distance is 6.0 m (6000 mm), the closest match in the 
Distance from screen (mm) column is 5943 mm. Looking across this row shows that a 
150 (about 3.8 m) screen is required.
All measurements are approximate and may vary from the actual sizes. 
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 15
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.
•  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 43 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 built-in mono speaker(s) 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 speaker(s).
The built-in speaker(s) will be muted (except for the Power On/Off Ring Tone) when 
the AUDIO OUT jack is connected.
•  The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See 
Connecting audio on page 16 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.
