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
projector's 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.
• Do not let the IR transmitter of the remote control be shined by sunlight or
fluorescent lamps directly.
• Please keep the remote controller away from fluorescent lamps for over 2 m or
the remote controller might become malfunction.
• If the remote control is close to Inverter-Type fluorescent lamps, it might become ineffective fr om time to time.
• If the remote control and the projector are within a very short distance, the remote control might become ineffective.
• When you aim at the screen, the effective distance is less than 5 m from the remote control to the screen and reflecting
the IR beams back to the projector. However, the effective range might change according to screens.
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

contact your physician or your poison control center.
• Dispose of the used battery with cellophane tape wrapping both ends of it.
EN-10
Positioning your projector
Choosing a location
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.
Your projector is designed to be installed in one of the possible installation locations:
ENGLISH
1. Front Table
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.
2. Rear Ta b le
Select this location with the projector placed near the
floor 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.
3. Rear Ceiling
Select this location with the projector suspended upsidedown from the ceiling behind the screen.
Note that a special rear projection screen and qualified
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. Front Ceiling
Select this location with the projector suspended upsidedown from the ceiling in front of the screen.
Purchase a qualified 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.
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.
4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9 (widescreen) aspect rat io image,
the projector can resize and scale a widescreen image to the projector's native aspect width. This will result in a
proportionally smaller height equivalent to 75% of the projector's native aspect height.
4:3 aspect image in a 4:3
aspect display area
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 center of the 4:3 projection
display area.
The projector should always be placed horizontally level (like flat on a ta ble), and positioned directly perpendicular
(90° right-angle square) to the horizontal center of the screen. This prevents image distortio n caused by angled
projections (or projecting onto angled surfaces).
16:9 aspect image scaled to
a 4:3 aspect display area
EN-11
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 . Thi s 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).
Y ou can see from the diagram on page 13, 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 project ed im age 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.
How to determine the position of the projector for a given screen size
1. Determine the aspect ratio of your screen, 16:9 or 4:3? If you have a 4:3 screen, refer to the table labeled
"(Standard)". If you have a 16:9 screen, refer to the table labeled "(16:9)".
2. Select your screen size.
3. Refer to the table and find the closest match to your screen size in the left columns labeled "Screen". Using this
value, look across this row to the right to find the corresponding average distance from screen value in the
column labeled "Distance from the screen: L". This is the projection distance.
4. On that same row, look across to the right column and make note of the "Hd" value. This will determine the final
vertical offset placement of the projector in relat ion to the edge of the screen.
5. The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the
distance from the screen determined in step 3 above, and offset by the value determined in step 4 above.
For example, if you are using a 4:3 aspect ratio, 100-inch screen, distance from the screen is 3.8 m and with a vertical
offset of 15 cm at Zoom position wide.
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 24 for details.
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 "(Standard)" or "(16:9)", and find the closest match to your measurement in the distance from
the screen column. If the min and max values are available on the table, 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". That is the projected imag e
size of the projector at that projection distance.
4. On that same row, look across to the right column and make note of the "Hd" 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 4.0 m and your screen aspect ratio is 4:3, the closest match in
the "Distance from the screen: L" column is from 3.8 m to 4.2 m. Looking across this row shows that a 100-inch
screen is required.

There is 3% tolerance among these numbers due to optical component variations. Mitsubishi recommends that if you intend to
permanently install the projector, you should physically test the projection size and distance using the actual projector in suit
before you permanently install it, so as to make allowance for this projector's optical characteristics. This will help you
determine the exact mounting position so that it best suits your installation location.

Connection
Notebook or desktop computer
RGB cable
or
Audio cable
Speakers
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. They are commercially available from
electronics stores.
Connecting a computer or monitor
Connecting a computer
The projector provides a RGB 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:
1. Take the supplied RGB cable a nd connect one end to the D-Sub output socket of the computer .
2. Connect the other end of the RGB cable to the COMPUTER-1 or COMPUTER-2 signal input socket of the
projector.
3. If you wish to make use of the projector speaker in your presentations, take a suitable audio cable and connect
one end of the cable to the audio output jack of the computer, and the other end to the AUDIO IN jack of the
projector.
4. If you wish, you can use another suitable audio cable and connect one end of the cable to the AUDIO OUT jack
of the projector, and the other end to your external speakers (not supplied).
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Adjusting
the sound" on page 30 for details.
The final connection path should be like that shown in the following diagram:
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 notebook's documentation to find your
notebook's key combination.

Connecting a monitor
Notebook or desktop computer
RGB cable
If you want to view your presentation close-up on a monitor as well as on the screen, you can connect the MONITOR
OUT signal output jack on the projector to an external monitor following the instructions below:
To connect the projector to a monitor:
1. Connect the projector to a computer as described in "Connecting a computer" on page 14.
2. Connect the RGB cable from the monitor to the MONITOR OUT jack of the projector.
3. Connect the other end of the cable to the MONITOR OUT jack on the projector.
• The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER-1 jack.
Connecting Video source devices
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) V ideo. See "Connecting a Component Video source device"
on page 16 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 V id eo. 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-V ideo sou rce device" on page 17 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 metho d s described here. See "Connecting a composite Video
source device" on page 18 for how to connect the projector to a composite Video device.
