							Introduction 14
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 15 degrees perpendicular 
to the projectors IR remote control sensor to 
function correctly. The distance between the remote 
control and the sensor should not exceed 7 meters 
(~ 23 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 
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 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
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.
16:10 is the native aspect ratio of this projector. 
The projector should always be placed horizontally level (like flat on a table), and 
positioned directly perpendicular (90° right-angle square) to the horizontal center of the 
screen. This prevents image distortion caused by angled projections (or projecting onto 
angled surfaces). 
The modern digital projector does not project directly forward (like older style reel-to-
reel film projectors did). Instead, digital projectors are designed to project at a slightly 
upward angle above the horizontal plane of the projector. This is so that they can be 
readily placed on a table and will project forward and upwards onto a screen positioned so 
that the bottom edge of the screen is above the level of the table (and everyone in the 
room can see the screen).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it 
projects at a slightly downward angle.
You can see from the diagram on page 16, that this type of projection causes the bottom 
edge of the projected image to be vertically offset from the horizontal plane of the 
projector. When ceiling mounted, this refers to the top edge of the projected image.
If the projector is positioned further away from the screen, the projected image size 
increases, and the vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account for 
both the projected image size and the vertical offset dimension, which are proportional to 
the projection distance.
BenQ has provided a table of screen size to assist you in determining the ideal location for 
your projector. Refer to  Projection dimensions on page 16 depending on the projector 
you are using. There are two dimensions to consider, the perpendicular horizontal distance 
from the center of the screen (projection distance), and the vertical offset height of the 
projector from the horizontal edge of the screen (offset).4:3 aspect image in a 16:10

Projection dimensions
Refer to Dimensions on page 69 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.

							Connection17
Connection
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.
Connecting the power
The projector must be used with the provided AC adapter. Damage caused by the use of an 
incorrect adapter is not covered under the warranty.
Using the AC adapter
1. Insert the plug from the AC adapter into the DC IN terminal.
2. Insert the appropriate end of the power cord into the AC adapter.
3. Insert the plug on the power cord into a wall outlet. Check that the Power LED 
indicator on the projector lights blue when using the AC adapter.

							Connection 18
Connecting a computer
The projector provides a VGA input socket that allows you to connect it to both IBM® 
compatibles and Macintosh® computers. A Mac adapter is needed if you are connecting 
legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer:
• Using a VGA cable
1. Take the supplied multi-input cable and connect one end to the D-Sub output socket 
of the computer.
2. Connect the other end of the multi-input cable to the PC/AV socket on the 
projector.
3. If you wish to make use of the projector speaker, take a suitable audio cable and 
connect one end of the cable to the audio output socket of the computer, and the 
other end to the audio input sockets of the multi-input cable.
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.

2. Connect the other end of the HDMI cable to the HDMI jack on the projector.
• Using a USB cable
1. Take a USB cable and connect the type A end to the USB output jack of the 
computer.
2. Connect the mini-B type end of the USB cable to the USB-DISPLAY jack on the 
projector. When you connect the projector to a computer, you can display 
computer’s im age o r transfer files from your computer to the internal mem or y of the 
projector.
3. If you select USB Display, follow the on-screen message to install the USB driver in 
your computer first.
4. If you select USB File Transfer, go to My Computer or Windows Explorer to access

							Connection 20To disconnect the projector from a computer:
i. Click  on the Windows Taskbar.
ii. Click the pop-up message.
iii. Disconnect the USB cable only when the message says that it is safe to remove 
the hardware.
• Do not disconnect the USB cable while the files are being copied, as this could result in loss 
of data or damage to the projector.
• The connection will not end if you have projector files open on the computer. Close all 
projector files and try again.
• Other versions of Windows operate similarly. Follow the correct procedure for removing a 
USB device from your computer safely for your version of Windows.
Connecting Video source devices
You need only connect the projector to a Video source device using just one of the above 
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:
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.
