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 14
Remote control effective range
Infra-Red (IR) remote control sensor is located on 
the front and the rear 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. 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 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 manufacturer’s 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 a table in front of the screen. 
This is the most common way to position 
the projector for quick setup and 
portability.2. Rear Table
Select this location with the projector 
placed on a 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.
3. Front Ceiling
Select this location with the projector 
suspended upside-down from the ceiling 
in front of the screen.
Purchase the BenQ Projector Ceiling 
Mounting 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.4. 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 Mounting 
Kit are required for this installation 
location.
*Set Rear Ceiling in the SYSTEM 
SETUP: Basic > Projector 
Installation menu after you turn the 
projector on.

Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and the 
video format each factors in the projected image size.
Projection dimensions
Refer to Dimensions on page 62 for the center of lens dimensions of this projector 
before calculating the appropriate position.

							Positioning your projector 18
There is 5% 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 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.
• 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.

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 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.
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 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.
