Setup & Connections
When connecting the projector to a compatible computer other than an IBM-PC (VGA/SVGA/XGA/SXGA) or
Macintosh (i.e. Workstation), a separate cable may be needed. Please contact your dealer for more information.
• Connecting computers other than the recommended types may result in damage to the projector, the computer, or both.
Connecting the Projector
Connecting other compatible computers
“Plug and Play” function
• This projector is compatible with VESA-standard DDC 1/DDC 2B. The projector and a VESA DDC compatible
computer will communicate their setting requirements, allowing for quick and easy setup.
• Before using the “Plug and Play” function, be sure to turn on the projector first and the connected computer last.
• The DDC, Plug and Play function of this projector operates only when used in conjunction with a VESA DDC compatible computer.
Connecting the Projector to Video Equipment
You can connect your projector to a VCR, laser disc player, DVD player, DTV decoder and other audiovisual
equipment.
CAUTION
• Always turn off the projector while connecting to audiovisual equipment, in order to protect both the projector and the
equipment being connected.
Connecting a video source (VCR, laser disc player, DTV decoder or DVD player)
using the standard video input
1Connect one end of the S-video cable to the S-VIDEO
INPUT 2 terminal, or one end of the video cable to the
VIDEO INPUT 3 terminal on the projector and the video
output terminal on the video source.
2To use the built-in audio system, connect the red and
white RCA connectors to the corresponding red and
white AUDIO INPUT terminals on the projector and the
audio output terminals on the video source.
The S-VIDEO INPUT 2 terminal uses a video signal system
in which the picture is separated into a color and a
luminance signal to realize a higher-quality image.
• For higher quality video, you may use the S-VIDEO INPUT 2 terminal on
the projector. S-video cable is sold separately.
• If your video equipment does not have an S-video output terminal, use
the composite video output terminal.

Operation
Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
Move the projector forward or backward if the edges of the image are distorted.
• The projector lens should be centered in the middle of the screen. If the lens center is not perpendicular to the screen, the image will be
distorted, making viewing difficult.
• Position the screen so that it is not in direct sunlight or room light. Light falling directly onto the screen washes out 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.
Setting up the Screen
Place the projector at the required distance from the screen according to the desired picture size. (See the table
below.)

							E-19
Operation
Setting up the Screen
Using the Adjustment Feet
You can adjust the height of the image by raising the projector with the
foot releases.
1Press the foot releases and lift the projector to the desired angle.
(Adjustable up to approximately 7° from the standard position.)
2Remove your hands from the foot releases. Once the adjustment
feet have locked in position, release the projector.
3If the screen is at an angle, the adjusters can be used to adjust
the angle of the image.
Returning the projector to its original position
While holding the projector, press the foot releases and slowly lower the projector
to its original position.
• When an adjustment is made, the image may become distorted (keystoned), depending
on the relative positions of the projector and the screen.
• Optimal image quality can be achieved when the projector is positioned perpendicular to the screen with all feet flat and level.
Reversed Image Setup
Projection using a mirror
• When the distance between the projector and screen
is not sufficient for normal rear projection, you can
use a mirror to reflect the image onto the screen.
• Place a mirror (normal flat type) in front of the lens.
• Project the normal image onto the mirror.
• The image reflected from the mirror is projected onto
the translucent screen.
Rear projection
• Place a translucent screen between the projector and
the audience.
• Use the projector’s menu system to reverse the
projected image. (See page 36 for use of this
function.)
CAUTION
• When using a mirror, be sure to carefully position both the projector and the mirror so the light does not shine into the eyes of
the audience.
Ceiling-mount Setup
• It is recommended that you use the optional Sharp ceiling-mount
bracket for this installation.
• Before mounting the projector, contact your nearest Authorized
Sharp Industrial LCD Products Dealer or Service Center to obtain
the recommended ceiling-mount bracket (sold separately). (AN-
PGCM80 ceiling-mount bracket, AN-EP101AP extension tube for
AN-PGCM80.)
• When the projector is in the inverted position, use the upper edge
of the screen as the base line.
• Use the projector’s menu system to select the appropriate projection
mode. (See page 36 for use of this function.)
CAUTION
• Do not press the foot releases when the adjustment feet are extended without firmly holding the projector.
• Do not hold the lens when lifting or lowering the projector.
• When lowering the projector, be careful not to get your fingers caught in the area between the adjustment feet and the
projector.
