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 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 si ze .  (See page  1 8 .)

•The distance from the screen to the projec- 
tor may vary depending on the size of the 
screen.   P.1 8
•The default setting can be used, when plac-
ing the projector in front of the screen. If the
projected image is reversed or inverted, re- 
adjust the setting to “Front” in “PRJ Mode”.

•Place the projector so that the horizontal line 
that passes through the center of the lens is
perpendicular to the screen.

Projecting a Reversed/Inverted Image
Projection from behind the screen

 Place a translucent screen between the projector and the 
audience.

 Reverse the image by setting  “Rear ” in  “PRJ Mode ”. See
page  60 for use of this function.
Projection using a mirror

 Place a mirror (normal flat type) in front of the lens.

 Reverse the image by setting  “Rear ” in  “PRJ Mode ”, when the
mirror is placed on the audience sid e.  See page  60  for use of
this function.
Info
• When using a mirror, be sure to carefully position both the pro- 
jector 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 Sharp 
Authorized Projector Dealer or Service Center to obtain the 
recommended ceiling-mount bracket (sold separately.) (AN-
PGCM90 ceiling-mount bracket, its AN-EP101B extension tube 
and AN-JT200 universal bracket, adaptor for non-level ceiling 
installation (for U.S.A.), BB-M20T ceiling adaptor, its BB-
NVHOLDER280, BB-NVHOLDER550, BB-NVHOLDER900

mount bracket, its AN-TK301/AN-TK201 and AN-TK302/AN-
TK202 extension tubes (for countries other than the U.S.A. and 
GERMANY))

 Be sure to adjust the position of the pro- 
jector to match the distance (H) from 
the lens center position (see page  1 8 )
to the lower edge of the image, when 
mounting the projector on 
the ceiling.

 Invert the image by 
setting  “Ceiling + Front ”
in  “PRJ Mode ”.
