2.3 Screen Size and Projection Distance Details
Select a distance from lens to screen that provides your desired screen size.
The recommended distance is 1.0 m (39.37inches)—13.1 m (515.75inches) 
.
Refer to the following table for setup.
* Use the approximate projection distance as a guide to setup.  Projection 
conditions and other factors can affect results.
Point:
A keystone correction will reduce screen size.

3.1 Connecting to a Computer
Computers which can be connected
Some computer models may not allow connection, and others may allow 
connection but not projection.
Make sure that the specifications of the computer you are using for connection 
meet the following two requirements.
[The computer must have a video signal output port]
Make sure that the computer has a port that outputs a video signal.
A port that outputs a video signal is called an RGB port, monitor port, or 
video port or the like.
Consult the section describing connection to an external monitor or the like 
in the instruction manual for the computer that you are using, and make sure 
that the computer has a video signal output port.
Computers with an integrated monitor and other components as well as 
notebook personal computers may require separate purchase of an external 
output port.
In other cases, an external output port cannot be attached.
[The resolution and frequency of the computer must be within the range of 
specifications shown on the following page]
The resolution and frequency of the video signal output by your computer 
must be compatible with your projector in order to allow projection (some 
computers allow partial projection, but clear projection cannot be obtained).
Check the resolution and frequency of the video signal in the instruction 
manual of the computer you are using for projection.




						

							23
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
 Before connecting, switch off power to the projector and computer.
 Check that cable and terminal 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 an optional Mac desktop adapter.
Point:
 When using the projector, do not bundle power cords and computer cables 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 a built-in speaker in your projector.
Your projector allows output at a maximum 1W.
Point:
 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 terminal style of your computers output 
terminal and the projectors Audio In terminal (stereo mini jack).

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

3.3 Providing Sound Through an External 
      Audio Device
Connecting the Audio Out terminal 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 3.5mm 
(0.14inches)  stereo mini-jack plug.
Point:
 Insertion of pin plugs into the audio output terminals provides automatic external 
output of audio.  Audio will no longer be output from the projector speaker.
 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 L/R audio 
terminals.
 Before purchasing an audio connection cable, thoroughly check the connection 
interface style of the external audio devices you are connecting.

3.4 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 (supplied with 
projector) to the projector.
Align the power cord connector with the 
power terminal on the projector and insert 
the connector firmly and completely into the 
terminal.
4.Insert the plug end of the power cord in an 
outlet.  The operation display indicator will 
light with an orange color.
Point:
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 On Off 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.
No-Signal is displayed.  
Depending on your settings, 
there may be no display.
(See page 51)
The operation display indicator 
lights green.
