Standard Ceiling Installation

Note

• 

The projector lens should be centred in the middle of the screen. If the horizontal line
passing through the lens centre 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 colours, making viewing difficult. Close
the curtains and dim the lights when setting up the screen in a sunny or bright room.

• 

A polarising screen cannot be used with this projector.

18

• 

Place the projector at the required distance from the screen
according to the desired picture size.

• 

The distance from the screen to the
projector may vary depending on the size of
the screen. 

• 

The default setting can be used, when
placing the projector in front of the screen. If
the projected image is reversed or inverted,
readjust the setting to “Front” in “PRJ
Mode”.

• 

Place the projector so that an imaginary
horizontal line that passes through the
centre of the lens is perpendicular to the
screen.

19

• 

Place a translucent screen between the projector and the audience.

• 

Reverse the image by setting “Rear” in “PRJ Mode”.

• 

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

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.

• 

It is recommended that you use the optional Sharp ceiling-mount bracket for this
installation. Before mounting the projector, contact your nearest Sharp Authorised
Projector Dealer or Service Centre to obtain the recommended ceiling-mount bracket
(sold separately.) (AN-C30T ceiling mount bracket, its AN-TK201 and AN-TK202
extension tubes)

• 

Be sure to adjust the position of the projector to match the distance (H) from the lens
centre position to the lower edge of the image, when mounting the projector on the
ceiling.

• 

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

The formula for picture size and projection distance
y1 = 0.1647x_0.1020
y2 = 0.1266x_0.0312
y3 = _0.0166x_0.0188
x: Picture size (diag.) (inches)
y1: Maximum projection distance (feet)
y2 : Minimum projection distance (feet)
y3 : Distance from the lens centre to the bottom of the image (H) (inches)

Note

• 

There is an error of ± 3% in the formula above.

• 

Values with a minus (–) sign indicate the distance of the lens centre below the bottom of the image.
