Connecting to a Computer
Using the Remote Control to Operate the Mouse Pointer (Wireless Mouse Function)
You can use the remote control as a wireless mouse to control the mouse 
pointer on the screen by using the accessory USB
g cable to connect the 
USB port of the computer to the [USB] port at the rear of the projector.
* When using the remote control as a wireless mouse, the [Page  ] and 
[Page  ] buttons on the remote control can be used to scroll back and 
forth through slides when projecting a PowerPoint presentation.

TIP
 The USB cable can only be connected to computers with a standard 
USB interface. If using a computer which is running Windows, the 
computer must have had a full version of Windows 98/2000/Me/XP 
Home Edition/XP Professional installed. If the computer is running 
a version of Windows 98/2000/Me/XP Home Edition/XP 
Professional that has been upgraded from an earlier version of 
Windows, correct operation cannot be guaranteed. 
 It may not be possible to use the wireless mouse function under some 
versions of both the Windows and Macintosh operating systems.
 Some computer settings may have to be changed in order for the 
mouse function to be used. Consult the documentation for the 
computer for further details.

Connecting to a Computer
Connecting an External Monitor
When analogue RGB signals from a computer are being projected, you can 
connect an external monitor to the projector in order to view the images on 
the external monitor at times such as when giving presentations.
Connect the external monitor using the cable that is provided with the 
monitor.
Cable provided with monitor
To [Monitor Out] port (black) Monitor port
TIP
 Digital RGB images from a computer and video images cannot be 
output to an external monitor.
 The setting gauge for keystone correction and the configuration 
menus and help menus are not output to the external monitor.

Connecting to a Video Source
Projecting Composite Video
g Images
Use a commercially- available A/V cable to make the connection.
CAUTION
When connecting the projector to other video sources, take the 
following precautions.
 Turn the power off for both the projector and the video source 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.

projected in unnatural colours. In such case, set the Computer 
Input in the configuration menu to Component Video.    p.81
 When connecting more than one device to the projector, use the 
[Comp] button on the remote control, or the [Computer/DVI] button 
on the projectors control panel to switch between devices after 
starting projection.   p.32

Connecting to a Video Source
Projecting RGB Video Images
RGB video is used when projecting RGB signals from a video source other 
than a computer that is connected to the projector. Either of the following 
two connection methods can be used. Use whichever method is suitable for 
the video equipments port.
Use the accessory computer cable to make the connections.If the RGB Output Port is a Mini D-Sub 15-pin Port (Example)To RGB output port

Playing Sound from the Video EquipmentThe projector has a built-in speaker with a maximum output of 5 W. You can 
output sound from the connected video equipment (such as a computer or 
video deck) through the projectors built-in speaker if the video equipment has 
an audio output port.
In the case of the [DVI] and [Computer] ports, the [Audio] port to use is the 
port that is in the same box as the port being used to input the video signals. 
For other ports, the [Audio] port matches the port in the same box that is being 
used to input the video signals.
Select the audio cable that is used for this connection from the following, 
depending on the shape of the other equipments port.
 If connecting to a stereo mini jack (such as the audio output port of a 
computer): Use a commercially-available stereo mini jack audio cable to 
make the connection.
 If connecting to an RCA pin jack ×2 (red/white) (such as the audio output 
port of video equipment): Use a commercially-available A/V cable to make 
the connection.

Playing Sound from the Video Equipment
TIP
 You can adjust the volume after projection has started.   p.52
 If the audio signal source is connected to the audio ports that are 
used in common with the [DVI] or [Computer] ports, the audio 
signals that are being input are output regardless of the image signal 
that is selected. The audio signals to be output using the Computer/
DVI Audio Input setting in the Audio menu can only be set to 
Computer or DVI.
 If using a commercially-available 2RCA (L/R)/stereo mini-jack 
audio cable, use one that is marked as No resistance. 
						

							28
Playing Sound from External SpeakersYou can connect speakers with built-in amplifiers to the projectors [Audio 
Out] port in order to enjoy a fuller quality of sound.
Use a commercially-available audio cable with pin jack ⇔ stereo mini jack 
(3.5 mm) plugs or similar.
Use an audio cable with a plugs that match the ports for the external audio 
equipment.To external audio equipment

When a stereo mini-jack audio cable is inserted into the [Audio Out] 
port, the sound will be output to external speakers. No sound will be 
output from the projectors built-in speaker at this time.
