Features of the Projector
Automatic keystone correction function
The vertical angle of the projector is
detected, so that any vertical keystone
distortion in the projected images can
be automatically corrected. (p.34)
Compact and lightweight
The projector has a compact body with a footprint the size of a B5 page
(19 (D) x 27.6 (W) x 7 (H) cm (7.5 (D) x 10.9 (w) x 2.8 (H))) and is light in weight
(approximately 1.9 kg. (4.2 lbs)), making it easy to carry.
Color mode function
The optimum images can be projected simply by selecting the image quality from the
following six preset settings according to the projection environment being used.
No other troublesome colour adjustments are necessary. (p.40, 47, 49)
•sRGB •Normal •Meeting
•Presentation •Theatre •Game
Automatic setup function
When projecting computer images, the signals from the connected computer are
detected automatically and adjusted so that the optimum images are projected. Even if
several people are giving presentations using the same projector, the optimum picture
quality can be obtained simply by disconnecting and reconnecting the computers.
Each individual setting can also be adjusted manually. (p.37)
Brilliant, attractive images
Despite its compact size, the projector can display images at high resolutions with a high
degree of luminance, providing beautifully clear images even in bright environments.
Easy to Operate
The accessory remote control can be used for operations such as pausing projection
(see "Freeze" on p.43) and zooming in on important areas of an image
(see "E-Zoom" on p.45). In addition, the remote control can be used to move the
pointer around on the computer screen during projection (see "Wireless Mouse
Function" on p.21). If using the wireless mouse function, you can use the remote control
to scroll back and forth through pages when projecting a PowerPoint presentation.

Before Using the Remote Control
Using the Remote Control and Remote Operating Range
When using the remote control for the first time, pull out the insulating tape that
is protruding from the battery holder. When the insulating tape is pulled out, the
remote control can then be used.
The remote control is used in the following way.
Procedure
Point the remote control light-emitting area toward one of the
remote control light-receiving areas on the projector and operate
the remote control buttons.
Tip :
• Do not allow sunlight or light from fluorescent lamps to shine directly onto the
projector's remote control light-receiving areas, otherwise it may interfere with the
reception of signals from the remote control.
• If delays in the responsiveness of the remote control occur or if it does not operate after
it has been used for some time, it probably means that the battery is getting flat. If this
happens, replace the battery with a new one. (p.74)
• When not using the remote control, place it into the remote control holder at the back of
the projector so that it does not get lost.

Installation
Setting Up the Projector
The projector supports the following four different projection methods,
allowing you to choose the best method for displaying your images.
Caution :
Before setting up the projector, be sure to first read the separate Safety Instructions/
World-Wide Warranty Terms.
* A special method of installation is required in order to suspend the projector from
the ceiling. Please contact the place of purchase if you would like to use this
installation method. The optional ceiling mount is required when installing the
projector to the ceiling. (p.82)
Tip :
When using rear/ceiling projection using a translucent screen, set the "Ceiling" or "Rear
Proj." command in the "Advanced" menu to match the installation method. (p.53)
• Front projection • Rear projection using a translucent
screen
• Front/ceiling projection • Rear/ceiling projection using a
translucent screen

15
Screen Size and Projection Distance
The distance between the projector and the screen determines the actual image
size.
While referring to the table below, position the projector so that the images are
projected onto the screen at the optimum size.
The values should be used as a guide for setting up the projector. The actual
values will vary depending on projection conditions and the zoom setting.
* When installing against a wall, leave a space of about 20 cm (7.9 in.) between the
projector and the wall.
Tip :
• The projector's lens allows a zoom ratio of up to about 1.16. The image size at the
maximum zoom setting is about 1.16 times bigger than the image size at the minimum
zoom setting.
• The image size will be reduced when keystone correction is carried out.

Connecting to a Computer
Caution :
When connecting the projector to a computer, be sure to check the following.
• Turn off the power for both the projector and the computer before connecting them. If
the power for either device is on at the time of connection, damage may result.
• Check the shapes of the cable connectors and the device ports before making the
connections. If you try to force a connector to fit a device port with a different shape or
number of terminals, damage to the connector or port may result.
Eligible Computers
The projector cannot be connected to some types of computer, or projection of
images may not be possible even if actual connection is possible. Make sure
that the computer you intend to use satisfies the conditions given below.
• Condition 1: The computer must have an image signal output port.
Check that the computer has a port such as an "RGB port", "monitor port" or
"CRT port" which can output image signals.
If the computer has a built-in monitor, or if using a laptop computer, it may
not be possible to connect the computer to the projector, or alternatively you
may need to purchase a separate external output port. Refer to the
documentation for your computer under a heading such as "Connecting an
external monitor" or similar for further details.
• Condition 2: The display resolution and frequency of the computer must be
listed in the "List of Supported Monitor Displays". See "Appendices: List of
Supported Monitor Displays"(p.88).
Some computers allow you to change the output resolution, so if necessary,
change the resolution to one that matches a setting in the "List of Supported
Monitor Displays", while referring to the documentation provided with the
computer.
Tip :
• You may need to purchase a separate adapter depending on the shape of the computer's
port. Refer to the documentation provided with the computer for further details.
• If the computer and projector are too far away from each other for the accessory
computer cable to reach, use the optional VGA-HD15 PC cable. See "Appendices:
Optional Accessories" (p.82)

17
Projecting Images from the Computer
The shape and specifications of the computer's monitor port will determine
what type of cable should be used. Check the following to see which type of
port your computer has.
Use the accessory computer cable to connect the Computer/Component Video
port at the rear of the projector to the monitor port of the computer.
Tip :
• Change the "Input Signal" setting in the "Video" menu to "RGB" after making the
connections. (p.47)
• If more than one external component is connected to the projector, use the [Source]
button on the projector's control panel or the [Computer] button on the remote control
to select the Computer port as the input source. (p.30)
• Do not bind the power cable and the computer cable together, otherwise image
interference or errors in operation may result.
