Playing Sound from the Video Equipment
The 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.
The audio cable to use for the connection can be either of the following, 
depending on the shape of the [Audio] port.To audio output ports
To [Audio] port RCA audio cable 
(accessory)
red
white
To audio output portAudio cable 
(accessory)
If the image signals are being input to 
the [Video] port
When video signals are being input 
to the [DVI] or [Computer] port
To [Audio] ports
TIP
 You can adjust the volume after projection has started.   p.55
 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. 
						

							31
Playing Sound from External Speakers
You 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
To [Audio Out] port
Audio cable 
(commercially-available)
TIP
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.

Turning the Projector On
If more than one external device is connected to the 
projector, use the remote control or projector control 
panel buttons to select the image source to be 
projected while referring to the following table.
You can also use the preview function to select the signal 
source.  p.36
*1 When these buttons are pressed once, the signal name that is currently 
set using the configuration menus appears on the screen. You can 
change the signal setting by repeatedly pressing the button while the 
signal name is displayed. The result of this switching will also be 
applied to the Computer Input or BNC Input setting in the Setting 
menu.
*2 The input signal will not change to the next signal source unless the 
[Computer/DVI] button is pressed while the current signal name is still 
being displayed on the screen.
If an input signal from either the [DVI] or [Computer] port is currently 
being projected, the name of this current input signal will be displayed 
on the screen when the [Computer/DVI] button is pressed once.
*3 The item selected using the Computer Input command in the 
Setting menu will appear. You can change the setting by pressing the 
[Comp] button on the remote control.
*4 The input signal will not change to the next signal unless the [Video/
BNC] button is pressed while the current signal name is still being 
displayed on the screen. 
If an input signal from either of the [BNC], [S-Video] or [Video] ports 
is currently being displayed, the name of this current input signal will 
be displayed on the screen when the [Video/BNC] button is pressed 
once.
*5 The item selected using the BNC Input command in the Setting 
menu will appear. You can change the source to the next source in order 
by pressing the [BNC] button on the remote control.

Selecting an Image Source While Viewing Projected Images (Preview Function)
The preview function lets you project the images from the currently-
selected image source and view them in a preview screen while selecting 
the signal source.
Use the remote control to carry out all preview function operations.PROCEDURE
Press the [Preview] button on the remote control.
After a short while, a preview screen such as the one shown in 
the illustration below will appear on the screen.
When the preview screen is being displayed, the frames for 
ports that have no image signal being input or which have a 
signal being input that is not supported will be solid blue.
Press the [Source] buttons on the remote control to select the 
image source to be projected in order to change the image.
TIP
 If only one signal source has been connected, the signals from that 
source will be projected without needing to press one of the [Source] 
buttons.
 If the No Signal. message does not disappear, check the 
connections again.
 If a laptop computer or a computer with an LCD screen has been 
connected to the projector, the images may not be projected straight 
away. After starting projection, check that the computer has been set 
up to output signals externally. 
The following table shows examples of how to toggle output settings. 
For details, refer to the section of the documentation provided with 
your computer under a heading such as External output, 
Connecting an external monitor or similar.
 If the same still picture is projected for a long period of time, the 
projected image may become burned in on the computer screen. You 
should avoid leaving the same image displayed for long periods.

TIP
 You can hear the sound for the images in the active window while 
the preview window is being displayed.
However, if images from a source that is connected to the 
[Computer] port or [DVI] port are being projected in the active 
window, the audio signals will be output according to the 
Computer/DVI Audio Input setting in the Audio menu.
 Images other than the image in the active window will be projected 
as still images.
 If you press the [Preview] button while E-Zoom function is active or 
real display is being used, these functions will be cancelled and the 
preview screen will be displayed. If you cancel the preview function 
without changing the input source, the projected images will return 
to the state they were at before the preview function was activated.
