CHAPTER 3: Installation

6. Make sure the power on the

LCD Panel is off, then plug the
power cord into a convenient
AC outlet.

7. Turn on the Macintosh, then

the LCD Panel.

NOTE: Follow this power-up sequence, or

the video signals might not be
synchronized correctly. The image
on the Color LCD Panel is made up
of red, green, and blue parts, and
the parts are synchronized to the
incoming video signal from the
computer. If there isn’t a video
signal from the computer—if you
turn on the LCD Panel while the
computer is still off, for example—
then the LCD Panel might lose
synchronization, and you’ll see a
split image of red, green, and blue.

To bring the LCD panel back to

normal, you can press the RESET
button on the panel or on the remote
control.

Avoid turning on the LCD Panel

for any length of time when no video
signal is present—that can reduce
the lifetime of the LCD.

8. Run a program on the

Macintosh that creates a
colorful image on the screen.
It’s easier to adjust the LCD
panel when it’s showing a
colorful image. Focus the
projector.

CAUTION

Make sure the LCD Panel’s
power adapter is completely
connected before you turn
on the projector. The cooling
fans in the LCD Panel won’t
work unless the power 
connected, and the h
from the projector cou
damage the Panel.

at the same time.

To go back t

o Mac II mode, press those two
buttons again.

3.3 Rear Projection

To use the LCD panel for rear
projection, just press the
FRONT/REAR button on the control
panel. To go back to front projection,
press the same button again.
