Ceiling-mount Setup

It is recommended that you use the optional
Sharp ceiling-mount bracket for this installa-
tion. Before mounting the projector, contact
your nearest Sharp Authorized Projector
Dealer or Service Center to obtain the rec-
ommended ceiling-mount bracket (sold sepa-
rately).
• AN-XRCM30 ceiling-mount bracket (for
U.S.A.).
• AN-60KT ceiling-mount bracket, its AN-
TK201 and AN-TK202 extension tubes (for
countries other than the U.S.A.).

Invert the image by setting “Ceiling + Front”
in “PRJ Mode”. See page 42 for use of this
function.
Setting up the Projector
Setting up the Projector
For optimal image quality, position the projector perpendicular to the screen with the projector’s feet
flat and level. Doing so will eliminate the need for Keystone correction and provide the best image
quality. (See page 31.)

Standard Setup (Front Projection)

Place the projector at the required distance from the screen according
to the desired picture size. (See page 20.)

outlet and turn off the devices to be connected. After making all connections, turn on the
projector and then the other devices. When connecting a computer, ensure that it is the last
device to be turned on after all the connections are made.
Ensure that you have read the operation manuals of the devices to be connected before making
connections.
* When using the ø3.5 mm mono audio cable, the volume level will be half of
when using the ø3.5 mm stereo audio cable.
• See page 58 “Computer Compatibility Chart” for a list of computer signals compatible with the projec-
tor. Use with computer signals other than those listed may cause some of the functions to not work.
• A Macintosh adaptor may be required for use with some Macintosh computers. Contact your near-
est Macintosh Dealer.
•Depending on the computer you are using, an image may not be projected unless the
computer’s external output port is switched on. (e.g. Press “Fn” and “F5” keys simultaneously
when using a SHARP notebook computer). Refer to the specific instructions in your computers
operation manual to enable your computer’s external output port.

Controlling the Projector by a Computer
When the RS-232C terminal on the projector is connected to a computer with a DIN-D-sub RS-
232C adaptor (optional: AN-A1RS) and an RS-232C serial control cable (cross type, commercially
available), the computer can be used to control the projector and check the status of the projector.
See page 54 for detail.

• See page 53 for connection of an RS-232C serial control cable.
Info
• Do not connect the RS-232C cable to a port other than the RS-232C terminal on the computer. This
may damage your computer or projector.
• Do not connect or disconnect an RS-232C serial control cable to or from the computer while it is on.
This may damage your computer.
