Before Using the Remote ControlInserting the Batteries
The batteries are not already inserted into the remote control at the time the 
projector is purchased. You will need to insert the batteries that are 
provided with the projector before the remote control can be used.PROCEDURE
Remove the battery cover.
While pushing the catch of the battery compartment cover, lift 
the cover up. 
Insert the batteries.
Check the positions of the (+) and (–) marks inside the battery 
holder to ensure that the batteries are inserted the correct way.Replace the battery cover.
Press the battery compartment cover until it clicks into place.
CAUTION
Be sure to read the Safety Instructions/World-Wide Warranty Terms 
before handling the batteries.1

TIP
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 batteries are becoming flat. Have two spare AAA-size alkali 
batteries ready to use when required. 
						

							13
Before Using the Remote ControlUsing the Remote Control and Remote Operating Range
The remote control is used in the following way.PROCEDUREPoint the remote control light-emitting area toward one of 
the remote control light-receiving areas on the projector 
and operate the remote control buttons. Using the Remote Control

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.
 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 batteries are getting flat. If this happens, replace the 
batteries with new ones. sp.12
 If any of the buttons on the remote control are pressed down for 
more than 30 seconds, the remote control stops to send signals 
(remote controls sleep mode) . The purpose of this is to prevent the 
batteries from being consumed due to something being placed on top 
of the remote control. 
When the button is released, normal remote control operation will 
resume.

Before Using the Remote Control
Use the remote control within the ranges indicated below. If the distance or 
angle between the remote control and the remote control light-receiving 
area is outside the normal operating range, the remote control may not 
work.

InstallationSetting Up the Projector
The projector supports the following four different projection methods, 
allowing you to choose the best method for displaying your images.
* A special method of installation is required for suspending the projector 
from the ceiling. Please contact your supplier if you would like to use 
this installation method. The optional ceiling mount is required when 
installing the projector on the ceiling. sp.93
CAUTION
Before setting up the projector, be sure to first read the separate 
Safety Instructions/World-Wide Warranty Terms. Front projection (Front projection)
 Rear projection using a translucent screen (Rear projection)
 Front/ceiling projection (Front/Ceiling projection)
 Rear/ceiling projection using a translucent screen 
(Rear/Ceiling projection)
TIP
When using ceiling projection or projection using a translucent 
screen, set the Projection command in the Extended menu to 
match the installation method. sp.62

InstallationScreen Size and Projection Distance
The distance between the projectors lens and the screen determines the 
actual image size.
While referring to the following table, 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.

Connecting to a Computer
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. 
sAppendices: List of Suppor ted Monitor Displays p.99.
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.
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.
 Do not bind the power cable and the connecting cable together. If the 
power cable and the connecting cable are bound together, image 
interference or errors in operation may result.
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.
 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. sAppendices: Optional Accessories p.93 
						

							19
Connecting to a ComputerProjecting 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 make the connection.If the Monitor Port is a Mini D-Sub 15-pin Port (Example)
Computer cable 
(accessory) To monitor port
To [Computer1/Component Video1] 
or [Computer2/Component Video2] 
port (blue)
TIP
 The input source is determined automatically based on the input 
signals. 
Some computer signals may be reproduced with different colours 
from the original images. If this happens, set the input source to 
Computer1 or Computer2. sp.55
 If more than one input source is connected to the projector at the 
same time, you can use button operations to select the signals to be 
projected. sp.33
