❷ Replacing the Color Wheel (included)
The projector comes with a color wheel (6-segment White) installed. An additional color wheel (6-segment Color) is
included with the accessories that come with the box.
TIP:
You can replace the pre-installed 6-segment White color wheel with the included 6-segment color wheel to create images with more
brilliant colors to match the source.
To replace the color wheel, refer to the following guide.
CAUTION:
Before replacing the color wheel, be sure to turn off the projector, wait until the cooling fans stop, and turn off the main
power switch. Allow 1 hour before replacing the color wheel.
• Do not touch the disk of the color wheel. Doing so may scratch the disk or leave fingerprints, causing the image
quality to degrade.
• Do not remove screws except when specified in the following instructions
• Heed the following information if you own two or more projectors:
When replacing or re-installing the color wheel, the original color wheel preinstalled or supplied as an accessory
must go back to its original projector. Your color wheel and projector color wheel cover are given an identification
number. Be sure to use the color wheel pre-installed or supplied with your projector to match its identification
number.
If you remove a color wheel from one projector and re-install it into another projector, performance may be com-
promised.
• Be sure turn off the main power switch before replacing the color wheel. Failure to do so may result in electrical
shock or damage to the projector, and cause an irregular color of the projected image.
