Connecting to a Video player, etc.
1. Connect one end (yellow) of the supplied audio/video
cable to the VIDEO terminal of the projector.
2. Connect one end (white and red) of the supplied audio/
video cable to the audio input terminals (L/MONO, R) of
the projector.
3. Connect the other end (yellow) of the audio/video cable to
the video output terminal of the video equipment.
4. Connect the other end (white and red) of the audio/video
cable to the audio output terminals (L, R) of the video
equipment.
•Also read the instruction manual of the equipment to be connected.
•Contact your dealer for details of connection.
When a TV tuner or VCR is connected:
When you use this projector with a TV tuner or VCR connected, no image may appear or a message of No Signal
may appear on the screen when you change the channel via any channel that is not being received. In such a
case, set the channels of the TV tuner or VCR again. To avoid such symptom, use the TV tuner or VCR with its
channel skip function (that is a function not to display channels that are not being received) enabled.
Connecting to a DVD player
To connect this projector to video equipment that has component video output terminals, such as a DVD player,
use the COMPONENT terminals.When the video equipment is equipped with the S-
video output terminal, make the connection as
follows.
1. Connect one end of the supplied  S-video cable to the S-
VIDEO terminal of the projector.
2. Connect the other end of the S-video cable to the S-video
output terminal of the video equipment.
3. Connect one end (white and red) of an audio cable to the
audio input terminals (L/MONO, R) of the projector.
4. Connect the other end (white and red) of the audio cable
to the audio output terminals (L, R) of the video equip-
ment.
•Images may not be projected correctly depending on the type of the DVD player you use.
•Though it may take some time before an image is displayed on the screen depending on the type of the input
signal, such symptom is not a malfunction.

Connecting to video equipment having a DVI-D terminal
You can project high-quality images by connecting the DVI terminal of this projector to video equipment having a
DVI-D output terminal. In addition, this projector supports HDCP and is able to receive encrypted digital video
data that are output from DVD players.
•For connection to the DVI-D terminal, use a commercially available DVI cable.
•Select DVI as the input source.
•Only RGB signals are supported. Component video signals are not supported.
•HDCP (High-bandwidth Digital Content Protection), developed by Intel Corporation, is a method to encrypt
digital video data for the purpose of copy protection.
•This projector uses stereo mini plug for its audio input.
•When DVI is selected as the input source, setting of COLOR, TINT, FINE SYNC., TRACKING and HOLD is
unavailable.
When you connect this projector and a DVI-Digital device (such as a DVD player) via the DVI
terminal, black color may appear light and pale, depending on the type of the connected device.
•This depends on the black level setting of the connected device. There are two kinds of methods to digitally
transfer image data, in which different black level settings are employed respectively. Therefore, the specifica-
tions of the signals output from DVD players differ, depending on the type of the digital data transfer method
they use.
•Some DVD players are provided with a function to switch the methods to output DVI-Digital signals. When
your DVD player is provided with such function, set it as follows.
NORMAL ➔ EXPAND or ENHANCED
•See the users guide of your DVD player for details.
•When your DVD player does not have such function, set BRIGHTNESS of this projector to -16.
B. Plugging in the power cord
1 Plug the attached power cord into the power cord inlet of
this projector.
2 Plug the other end of the power cord into a power outlet.
•The power cords for use in the U.S. and Europe are included with this projector. Use the appropriate one for
your country.
•This projector uses the power plug of three-pin grounding type. Do not take away the grounding pin from the
power plug. If the power plug doesn’t fit your wall outlet, ask an electrician to change the wall outlet.
•The provided power cord for the U.S. is rated at 120 V. Never connect this cord to any outlet or power supply
using other voltages or frequencies than rated. If you use a power supply using other voltage than rated,
prepare an appropriate power cord separately.

•Do not cover the lens with the lens cap while the lamp is on. Do not strip off the aluminium sheet inside
the lens cap.
3. Select an input source.
•Press the VIDEO button on the projector or the VIDEO or COMPONENT button on the remote control
that is corresponding to the terminal in use.
•The input source is switched between VIDEO, S-VIDEO and COMPONENT at every press of the VIDEO
button on the projector.
•The input source is switched between VIDEO and S-VIDEO at every press of the VIDEO button on the
remote control.
•Though it may take some time before an image is displayed on the screen depending on the type of the
input signal, such symptom is not a malfunction.
•Some images become easier to view when the setting of aspect ratio is changed. (See Page 17.)
4. Adjust the position of the projector to keep an appropriate projection distance with which images are projected
in their specified sizes.
5. Adjust the position of the projector so that the projector and the screen are perpendicular to each other. (See
Page 10.)
•When the projector cannot be positioned perpendicularly to the screen, adjust the projection angle. (See
Page 10.)
6. Adjust the size of the projected image by turning the ZOOM ring.
7. Adjust the focus by turning the FOCUS ring.
Repeat steps 4 to 7, if necessary.
Important :
•When a 4:3 image is kept displayed for a long time before displaying 16:9 image, the afterimages of the black
bars may appear on the 16:9 image screen. Consult your dealer in this case.
•Do not display a still picture for a long time because the afterimages may persist on the screen.
