Remote control effective range
Infra-Red (IR) remote control sensor is located on the front of the projector. The remote 
control must be held at an angle within 30 degrees perpendicular to the projectors IR 
remote control sensor to function correctly. The distance between the remote control 
and the sensor should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensor 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

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 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 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.
Projection dimensions 
Refer to Dimensions on page 52 for the center of lens dimensions of this projector 
before calculating the appropriate position.
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 41  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 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. An y stereo audio input (if provided), is mixed 
into a common mono audio output  through the projector speakers.
The built-in speaker will be muted 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.
