Note: When reassembling, be careful not to tighten
the screws too much. Otherwise the color wheel
mat come in contact with other components
nearby and fail to rotate. Readjustment will be
needed if the color wheel and the wheel sensor
have been replaced. (Refer to page __.)

Precautions in replacing and handling the lamp
1. Be sure to unplug the power cable before starting the procedure. (For prevention of electric shock)
2. Make sure that the lamp has cooled down before replacement. (For prevention of burns)
3. Do not give intense shock or vibration to the lamp. (For prevention of breakage and injury)
4. Do not disassemble the lamp.

The AC light source lamp flickers 300 times per second.
This color filter splits the light into RGB and W components.
The W (White) component contributes to the reproduction
of bright white color. The rotation-detecting sensor should
get in sync with the timing to turn off the lamp at the seam
of color filter. The maximum rotating speed is 7200 rpm.

This lens condenses the light that is split in RGB and W
components by the color filter, and projects it to the
effective area of the reflection mirror 1. Adoption of the
light tunnel has enhanced the illuminance ratio in
peripheral area of image, reducing the difference in
brightness between screen center and peripheries. The
image can be reproduced clearly at every corner of the
screen.
