Connecting to Video
Equipment Using an
S-video, a Composite
Video or an Audio Cable
Using an S-video, video, or audio cable, a VCR,
laser disc player or other audio-visual equipment
can be connected to INPUT 2, INPUT 3 and AU-
DIO input terminals.
1Connect the projector to the
video equipment using an S-
video cable or a composite video
cable (both commercially avail-
able).
2Connect the projector to the
video equipment using a ø3.5
mm minijack to RCA audio cable
(commercially available).
Note
•The INPUT 2 (S-VIDEO) terminal uses a
video signal system in which the picture is
separated into color and luminance signals
to realize a higher-quality image. To view a
higher-quality image, use a commercially
available S-video cable to connect the IN-
PUT 2 terminal on the projector and the S-
video output terminal on the video equip-
ment.
•A ø3.5 mm minijack to RCA audio cable
(commercially available) is required for au-
dio input.

Connecting to a
Computer Using a DIN-D-
sub RS-232C Adaptor
and an RS-232C Serial
Control Cable
When the RS-232C terminal on the projector is
connected to a computer with a DIN-D-sub RS-
232C adaptor and an RS-232C serial control
cable (cross type, sold separately), the computer
can be used to control the projector and check
the status of the projector. See page 61 for de-
tails.
1Connect the supplied DIN-D-sub
RS-232C adaptor to an RS-232C
serial control cable (sold sepa-
rately).
2Use the above cables to connect
the projector and the computer.
Note
•Do not connect or disconnect an RS-232C
serial control cable to or from the computer
while it is on. This may damage your com-
puter.
•The RS-232C function may not operate if
your computer terminal is not correctly set
up. Refer to the operation manual of the
computer for details.
•See page 60 for connection of an RS-232C
serial control cable.

Setup
Using the Adjustment
Feet
The height of the projector can be adjusted us-
ing the adjustment feet at the front and rear of
the projector when the surface the projector is
placed on is uneven or when the screen is
slanted.
The projection of the image can be made higher
by adjusting the projector when it is in a lower
place than the screen.
1While pressing the foot releases
on both sides, lift the projector
to adjust its height and then re-
move your fingers from the foot
releases.
2Rotate the adjustment feet at the
front of the projector for fine
adjustment.
•You can adjust the projection by using
the rear adjustment foot on the bottom
of the projector when the projector is po-
sitioned at the higher place than the
screen.
Note
•The Keystone Correction will be automatically
performed when the projector is tilted. If you
want to adjust the Keystone Correction
manually, see page 29. (For details on set-
ting of the Keystone Correction, see page 44.)
•When returning the projector to its original
position, hold the projector firmly, press the
foot releases and then gently lower it.
•The projector is adjustable up to approxi-
mately 12 degrees at the front and 3 degrees
at the back from the standard position.
Info
•Do not press the foot releases when the ad-
justment feet are extended without firmly
holding the projector.
•Do not hold the lens when lifting or lower-
ing the projector.
•When lowering the projector, be careful not
to get your fingers caught in the area between
the adjustment foot and the projector.

Example of standard setup
Setting up the Screen
Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
Note
•The projector lens should be centered in the middle of the screen. If the horizontal line passing through the
lens center is not perpendicular to the screen, the image will be distorted, making viewing difficult.
•For an optimal image, position the screen so that it is not in direct sunlight or room light. Light falling directly
on the screen washes out the colors, making viewing difficult. Close the curtains and dim the lights when
setting up the screen in a sunny or bright room.
•A polarizing screen cannot be used with this projector.
Standard Setup (Front Projection)

Place the projector at the required distance from
the screen according to the desired picture size.
(See page 24.)
Side View
Top View
•The distance from the screen to the projector
may vary depending on the size of the screen.
P.24
•The default setting can be used, when placing the
projector in front of the screen. If the projected im-
age is reversed or inverted, readjust the setting to
“Front” in the “PRJ Mode” menu.P.50
•Place the projector so that an imaginary horizontal
line that passes through the center of the lens is
perpendicular to the screen.
