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.
1 Press the foot releases and lift the projector to the desired angle.
(Adjustable up to approximately 7° from the standard position.)
2 Remove your hands from the foot releases. Once the adjustment
feet have locked in position, release the projector.
3 If 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.
