Remote control effective range
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.
Installing or replacing the remote control battery
• Avoid excessive heat and humidity. 
• There may be danger of damage to the remote and injury to those nearby if the battery is 
incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the manufacturer. 
• Dispose of the used battery according to your local regulations.
• 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.
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 of the 
projector’s IR remote control sensors to 
function correctly. The distance between 
the remote control and the sensors should 
not exceed 6 meters (~ 20 feet).

Installation
Choosing a location
Your projector is designed to be installed in one of two possible installation locations: 
1. Floor in front of screen; or
2. Floor at rear of screen
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.
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.
The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 
aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect 
ratio image, the projector can resize and scale a widescreen image to the projectors native 
aspect width. This will result in a proportionally smaller height equivalent to 75% of the 
projectors native aspect height.
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed 
by this projector. This will be seen as darkened (unlit) bars along the top and bottom 
(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying 
a scaled 16:9 aspect image in the vertical centre of the 4:3 projection display area.
When determining the position of your projector, you should consider its intended use and 
input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect 
signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height 
than that of the scaled 16:9 aspect image projection area).
IMPORTANT: Do not select a permanent projector position based upon a 16:9 projection if you 
will ever need to select an input other than composite Video being fed a 16:9 aspect signal.
I. Floor front: Select this location with the 
projector placed near the floor in front of the 
screen. This is the most common way to position 
the projector for quick setup and portability.
II. Floor rear: Select this location with the 
projector placed near the floor behind the screen.
Note that a special rear projection screen is 
required. Set  in the Advance > Mirror 
menu after you turn the projector on.

The projector should always be placed horizontally level (like flat on a table), and 
positioned directly perpendicular (90° right-angle square) to the horizontal centre 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).
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. 
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 directly 
proportional to the projection distance.
XD90U has provided a table of 4:3-aspect-ratio screen sizes (see Screen size chart on 
page 16) to assist you in determining the ideal location for your projector. There are two 
dimensions to consider, the perpendicular horizontal distance from the centre of the screen 
(projection distance), and the vertical offset height of the projector from the horizontal edge 
of the screen (offset).
How to determine the position of the projector for a given
screen size
1. Select your screen size.
2. Refer to the table on page 16 and find the closest match to your screen size in the left 
columns labelled 4:3 Screen Diagonal and 4:3 Aspect in mm. Using this value, look 
across this row to the right to find the corresponding average distance from screen 
value in the column labelled Average. This is the projection distance.
3. On that same row, look across to the right column and make note of the vertical Offset 
value. This will determine the final vertical offset placement of the projector in 
relation to the edge of the screen.
4. The recommended position for the projector is aligned perpendicular to the horizontal 
centre of the screen, at the distance from the screen determined in step 2 above, and 
offset by the value determined in step 3 above.
For example, if you are using a 120-inch screen, the average projection distance is 4757 mm 
and with a vertical offset of 229 mm.
If you place the projector in a different position (to that recommended), you will have to tilt 
it down or up to center the image on the screen. In these situations, some image distortion 
will occur. Use the Keystone function to correct the distortion. See Correcting keystone 
on page 25 for keystone correction.

How to determine the recommended screen size for a
given distance
This method can be used for situations where you have purchased this projector and would 
like to know what screen size will fit in your room. The maximum screen size is limited by 
the physical space available in your room.
1. Measure the distance between the projector and where you want to position the 
screen. This is the projection distance.
2. Refer to the table on page 16 and find the closest match to your measurement in the 
average distance from screen column labelled Average. Check that your measured 
distance is between the min and max distances listed on either side of the average 
distance value.
3. Using this value, look across that row to the left to find the corresponding screen 
diameter listed in that row. That is the projected image size of the projector at that 
projection distance.
4. On that same row, look across to the right column and make note of the vertical Offset 
value. This will determine the final placement of the screen in relation to the 
horizontal plane of the projector.
For example, if your measured projection distance was 4.5m (4500mm), the closest match 
in the Average column is 4682mm. Looking across this row shows that a 3000mm (3m) 
screen is required. If you can only obtain imperial sized screens, the listed screen sizes on 
either side of the 3m screen are the 9 and 10 screens. 
Checking the min and max projection distance values for the these (9 & 10) sizes, indicates 
that the 4.5m measured projection distance will fit these screens too. The projector can be 
adjusted (using the zoom control) to display on these different screen sizes at that projection 
distance. Be aware that these different screens have different vertical offset values.

Basic Connection
When connecting a signal source to the projector, be sure to:
• Turn all equipment off before making any connections.
• Use the correct signal cables for each source.
• Ensure the cables are firmly inserted. 
• In the connections shown below, some cables may not be included with the projector (see 
What’s included in the box on page 47). They are commercially available from electronics 
stores.
• This projector has no speaker or built-in support for audio reproduction.
Connecting a computer
The projector provides a VGA input socket that allows you to connect it to a notebook or 
desktop computer.
Additionally, you can also connect the projector to a computer via the USB cable so you can 
perform paging operations of the application on the PC or notebook. (see Remote paging 
operations on page 27).
To connect the projector to a notebook or desktop computer:
1. Take the supplied RGB cable and connect one end to the D-Sub output socket of the 
computer.
2. Connect the other end of the RGB cable to the D-SUB/COMP IN signal input socket 
on the projector.
3. If you wish to use the remote paging function (see Remote paging operations on 
page 27), take the supplied USB cable and connect the larger end to the USB port of 
the computer, and the smaller end to the USB socket on the projector.
The final connection path should be like that shown in the following diagram:
• A Mac adapter (an optional accessory) is needed if you are connecting legacy version (http:/
/www.info.apple.com/usen/legacy/) Macintosh computers.
• Many notebook computers 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 computer. Press FN and the labeled function key simultaneously. Refer to your 
notebook computer’s documentation to find your notebook computer’s key combination.

Connecting Video source devices
This section describes how to connect the projector to Video source devices using video 
cables. Video cable connections are recommended for Video presentations.
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
• Component Video
•S-Video
• Video (composite)
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:
Best video quality
The best available video connection method is Component Video (not to be confused with 
composite Video). Digital TV tuner and DVD players output Component Video natively, so 
if available on your devices, this should be your connection method of choice in preference 
to (composite) Video.
See Connecting a Component Video source device on page 19 for how to connect the 
projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard composite Video. 
If you have both composite Video and S-Video output terminals on your Video source 
device, you should elect to use the S-Video option.
See Connecting an S-Video source device on page 20 for how to connect the projector to 
an S-Video device.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but less than 
optimal result from your projector, being the least video quality of the available methods 
described here.
See Connecting a composite Video source device on page 21 for how to connect the 
projector to a composite Video device.

ENGLISH
Connecting a Component Video source device
Examine your Video source device to determine if it has a set of unused Component Video 
output sockets available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a Component Video source device
1. Take the (optional accessory) Component Video to VGA (D-Sub) adaptor cable and 
connect the end with 3 RCA type connectors to the Component Video output sockets 
of the Video source device. Match the color of the plugs to the color of the sockets; 
green to green, blue to blue, and red to red.
2. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable (with a 
D-Sub type connector) to the D-SUB/COMP IN socket on the projector.
The final connection path should be like that shown in the following diagram:
Component Video is the only video output that delivers native 16:9 aspect ratio picture.
If you connect the projector to a High Definition TV (HDTV) tuner, the following standards 
are supported:
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.

Connecting an S-Video source device
Examine your Video source device to determine if it has an unused S-Video output socket 
available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an S-Video source device
1. Take an appropriate S-Video cable (not supplied) and connect one end to the S-Video 
output socket of the Video source device.
2. Connect the other end of the S-Video cable to the S-VIDEO socket on the projector.
The final connection path should be like that shown in the following diagram:
• 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.
• If you have already made a Component Video connection between the projector and this S-
Video source device using Component Video connections, you need not connect to this 
device using an S-Video connection as this makes an unnecessary second connection of 
poorer picture quality. See Connecting Video source devices on page 18 for details.
