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 
projectors remote control light-receiving areas, otherwise it may interfere with the 
reception of signals from the remote control.
 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 :
When setting up the projector, be sure to first read the Safety Instructions/ World-Wide 
Warranty Terms for information on the safety instructions that must be observed at this 
time.
* 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.84)
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.54)

screen

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 image size 
is smaller than the screen size.
* The value for the projection distance should be used as a guide for setting up the 
projector. The actual distance will vary depending on projection conditions.
Tip :
 The projectors 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.Recommended distance1.0 m - 11.7 m (3.2ft. - 38.5ft.)

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 Appendix: List of 
Supported Monitor Displays(p.90)
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 computers 
port. Refer to the documentation provided with the computer for further details.
 A commercially-available adapter is required in order to connect the projector to a 
Macintosh computer.
 If the computer and projector are too far away from each other for the accessory 
computer cable to reach, use the optional computer cable. See Appendix: Optional 
Accessories (p.84) 
						

							17
Projecting Images from the Computer
The shape and specifications of the computers 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.49)
 If more than one external component is connected to the projector, use the [Source] 
button on the projectors 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 cord and the computer cable together, otherwise image 
interference or errors in operation may result.
