Reversed Image and Ceiling-mount Setups
Using the Reverse/Invert Image Function makes the following setups possible. See page 22 for use of this func-
tion.
Example of a reversed image setup
¥ By placing a mirror (normal flat type) in front of the lens and using the horizontal image reverse function, the image re-
flected from the mirror can be projected onto the screen.
¥ Rear projection with a rear projection screen is also possible when using the horizontal image reverse function.

operate the computer, plug the supplied mouse control cable from the remote mouse receiver to the computer.
CAUTION
¥ Before connecting, be sure to turn both the projector and the computer off. After making all connections, turn the pro-
jector on first. The computer should always be turned on last.
¥ Please carefully read the operation manual of the computer you will be connecting.
¥ Refer to page 35 ÒInput Signals (Recommended Timing)Ó for a list of computers connectable to the projector. Use with computers
other than those listed may cause some of the functions not to work.
¥ When connecting to a Macintosh Series computer, use the supplied Macintosh adaptor.

¥ When the RS-232C port on the projector is connected to a computer with an RS-232C cable (cross type, sold
separately), the computer can be used to control the projector and check the status of the projector. See
pages 33 and 34 for details.
CAUTION
¥ Do not connect or remove the mouse control cables or RS-232C cable to or from the computer while it is on. This may damage your
computer.
¥ The wireless mouse functions can operate computers compatible with IBM PS/2, serial (RS-232C) or Apple ADB type mouse systems.
¥ The wireless mouse or RS-232C function may not operate if your computer port is not correctly set up. Please refer to the operation
manual of the computer for details on setting up/installing the correct mouse driver.

1,024 @ 768 maximum resolution
Plug one end of the supplied computer cable
into the COMPUTER INPUT port on the pro-
jector and the other end into the RGB signal
output port (Monitor Out) on the computer, and
secure the plugs by tightening the thumb
screws.
¥ This connection can be made only when using a com-
puter with a VGA/SVGA/XGA or Mac display output port.
b. Connecting a Macintosh Series com-
puter
640 @ 480 or 832 @ 624 resolution
1. Set the proper switches on the supplied
Macintosh adaptor.
¥ For 640 2 480 resolution, set switches 1
and 2 to ÒONÓ and 3, 4, 5 and 6 to ÒOFFÓ.
¥ For 832 2 624 resolution, set switches 2
and 4 to ÒONÓ and 1, 3, 5 and 6 to ÒOFFÓ.
2. Connect the supplied Macintosh adaptor to
the supplied computer cable and the RGB
signal output port (Monitor Out) on your
Macintosh Series computer, as shown on
the left, and secure the plugs by tightening
the thumb screws.
3. Firmly plug the other end of the supplied
computer cable into the COMPUTER INPUT
port on the projector and secure the plugs
by tightening the thumb screws.
¥ Once the adaptor is connected to a computer and the
computer is turned on, the display mode cannot be
changed even if the switches on the adaptor are reset.
¥ The supplied Macintosh adaptor is only for use with
H-SYNC and V-SYNC output. When connecting a Macin-
tosh Series computer that only outputs C-SYNC, use a C-
SYNC output adaptor (sold separately).
c. Connecting other compatible com-
puters
When connecting the projector to a compatible
computer other than an IBM-PC (VGA/SVGA/
XGA) or Macintosh series, 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 com-
puter, or both.

Lamp/Maintenance Indicators
Lamp
The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environ-
ment. When the lamp has been used for 1,900 hours, the LAMP REPLACEMENT indicator will light red and
ÒLAMPÓ will flash in yellow on the screen. It is recommended that the lamp be replaced after 1,900 cumulative
hours of use or when you notice a significant deterioration of the picture and color quality.
If the lamp has been used for 2,000 hours, the projector power will automatically turn off and the projector will
enter standby mode. If you turn on the power after the lamp has been used for 2,000 hours, ÒLAMPÓ will flash in
red on the screen and the power will turn off. See pages 30 and 31 for replacing the lamp. The lamp usage time
can be checked with the On-screen Display (see page 19).
¥ As the usage environment can vary significantly, the projector lamp may not operate for 2,000 hours.
CAUTION
¥ Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.

¥ There are two warning lights: a TEMPERATURE WARNING indicator
which warns that the projector is too hot, and a LAMP REPLACE-
MENT indicator which lets you know when to change the lamp.
¥ If a problem occurs, either the TEMPERATURE WARNING indicator
or the LAMP REPLACEMENT indicator will light up red, and the
power will shut off. After turning off the power, follow the procedures
given below.
¥ If the TEMPERATURE WARNING indicator lights up, follow the above possible solutions and then wait until the projector
has cooled down completely before turning the power back on. (At least 5 minutes.)
¥ If the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicator may be
triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet and put it
back in again.Problem
