Compatible Mode Chart for Connectable Computers
If the resolution and frequency of the video signals which are output from the 
computer do not correspond to any of the values in the table below, those video 
signals cannot be projected. (In some cases it may be possible to project such 
signals, but they will not produce clear images.)
Check the instruction manual for the computer for details on the resolution and 
frequency of the video signals.
Furthermore, some computers may let you change the output resolution. If this 
is the case, change the resolution to a value in the table below.

Connecting to a Computer
Tip:
 Before connecting, switch off power to the projector and computer.
 Check that cable and port interfaces match each other.
[Projecting Computer Video]
You can make presentations on a large screen by projecting computer video 
from your projector.
* If your computer port style is not a mini D-Sub 15-pin interface, use a connection 
adapter that provides this interface.
When connecting to a Macintosh, you may need to use the optional Mac adapter.
Tip:
 When connected do not bind the power cord and the computer cable together.
 Some computer models may require a connection adapter during connection. Consult 
your computer instruction manual or the computer vendor.
[Outputting Computer Audio From Your Projector]
You can output computer audio from the built-in speaker in your projector.
Your projector allows output at a maximum 1W.
Tip:
 When computer video has been selected or when audio input is specified on the 
computer by menu, your projector outputs an audio signal from the computer.
 Purchase an audio cable that matches the port style of your computers output port 
and the projectors Audio In port (stereo mini jack).

[Inputting a Component Video Image Signal]
If using a component video cable
Tip:
 When projecting a component video image, select YCbCr or YPbPr in the Video 
> Input Signal menu.
Select YCbCr if using a DVD player,  and select YPbPr if using a HDTV video 
source.
 To change the aspect ratio of the projected image between 4:3 and 16:9, select Video 
> Aspect Ratio menu.

Providing Sound Through an External 
Audio Device
Connecting the Audio Out port of your projector to a PA system, active speaker 
system, or other speakers with built-in amplifiers provides powerful, pleasing 
sound.
Use a separately sold audio connection cable (pin ring) connecting to a 
0.14inches (3.5mm)  stereo mini-jack plug.
Tip:
 When a cable is connected at the 
Audio Out port the sound output will be switched from 
the built-in speaker to external sound output.
 Though the projector outputs audio for projected video images, in the case of A/V 
devices, the audio output corresponds to the audio devices connected to the Audio 
ports.
 Before purchasing an audio connection cable, thoroughly check the connection 
interface style of the external audio devices you are connecting.

Projecting Images
Here we begin projecting images from an A/V device.
Preparation
Warning:
 Never look into the lens when the projector is switched on.  The intense light can 
damage your vision.
 Use only the power cord supplied.  Use of other cables may cause fire or electric 
shock.
Caution:
Do not attempt projection with the lens cover in place.  Heat may deform the lens 
cover.
1.Check that the projector and computer or A/
V device are connected.
2.Remove the lens cover.
3.Attach the power cord (accessory) to the 
projector.
Align the power cord connector with the 
power inlet on the projector and insert the 
connector firmly and completely into the 
inlet.
4.Insert the plug end of the power cord in an 
outlet.  The operation display indicator will 
light with an orange color.
Tip:
Buttons cannot be operated while the operation 
display indicator is flashing orange.

Projection
When preparations are complete, you are ready for projection.
1.To use the remote control, turn the remote 
control R/C switch to On.
2.Press the Power button to switch power on.
The operation display indicator begins to 
flash green, and projection begins.
After approximately 30 seconds, the 
operation display indicator changes from 
flashing green to steady green.
Projector Remote control
No-Signal is displayed.  
Depending on your settings, 
there may be no display.
(See page 47)

3.Press the Source button on the projector or 
the Computer, S-Video or Video button on 
the remote control to select the video source 
you wish to project.
Each time the Source button on the projector 
is pressed, the video source cycles between 
Computer, S-Video and Video.
If there is no input at the S-Video port, the 
Source button switches the video source 
from Computer to Video.
Tip:
If projecting a component video picture, change 
the setting to Computer.
4.Switch on power to the computer or A/V 
device to begin projection.
The No-Signal display disappears, and a 
video signal from the computer or A/V 
device is projected.
Tip:
 If the No-Signal display remains, check the 
connections again.
 If the same static image is projected for some 
time, the video projection may contain an 
afterimage.

[Settings for laptop and integrated LCD computers (when connected)]
When a laptop or integrated LCD computer is connected to the projector, 
some computers require key commands or settings to change the output 
destination of a video signal.
Keep Fn depressed while pressing F0 to change the setting.
For details, consult the instruction manual of the computer you are using.
Tip:
Some computers may not be able to have images displayed on the computer screen at 
the same time as they are being projected. In such cases, use only external output.
