Use the RGBCMY settings to adjust the hue, saturation, and brightness of the six color 
components (red, green, blue, cyan, magenta, yellow). After adjusting each color, press 
Esc to move to another menu option. You can also access this setting by pressing the 
RGBCMY button on the remote control. See page 31 for more information. 
■Gamma
Note: This setting cannot be used when the Color Mode is set to x.v.Color (see page 29).
You can select from five gamma settings (2.0 to 2.4) or customize your own setting from 
your image or a displayed graph. Lower values will increase the contrast of dark areas, but 
tend to blur the bright areas. Higher values will darken the light areas.
You can also access this setting by pressing the 
Gamma button on the remote control. 
See page 30 for more information.
■Contrast Enhancement (Home Cinema 8500 UB only)
Note: This setting cannot be used when the Color Mode is set to x.v.Color (see page 29).
This setting automatically enhances contrast by calculating based on the current contrast. 
You can select from 3 levels of contrast enhancement.
■Super-resolution (Home Cinema 8500 UB only)
This setting sharpens blurred images, enhancing the apparent detail of the image. You can 
select from 3 levels of enhancement. Note that intentionally blurred parts of the image, 
such as out-of-focus backgrounds, may become sharper.
Adjustments for Computer Images
In addition to the settings described previously, you can adjust the Tracking and Sync settings 
for analog RGB computer images. Normally, these settings are adjusted automatically by the 
projector. If you notice that the image is blurry or contains dark vertical bands, you may need 
to adjust the settings yourself.
■Auto Setup
Leave this setting on so that the projector automatically adjusts the tracking, sync, and 
position of the image.

adjust the tracking when the image contains a lot of fine detail

make sure the tracking is properly adjusted first.

Maintenance
Your projector needs little maintenance. All you need to do on a regular basis is keep the lens 
clean. You also may need to clean the air filter to prevent overheating.
Warning: Before you clean any part of the projector, turn it off and unplug the power cord. Never 
open any cover on the projector, except the lamp and filter covers. Dangerous electrical voltages 
in the projector can injure you severely. Do not try to service this product yourself, except as 
specifically explained in this User’s Guide. 
The only parts you should replace are the air filter and the lamp. If another part needs 
replacing, contact your dealer or a qualified servicer.
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on 
the surface. 
■Use a blower brush that is designed for camera 
equipment to remove dust from the lens.
■To remove dirt or smears, use a lens cloth or 
tissue. If necessary, moisten the cloth with lens 
cleaner and gently wipe the lens surface.
Caution: Never rub the lens with abrasive materials. Use 
only lens cleaning fluids that are designed for cleaning 
optics. 
						

							50Maintenance
Cleaning the Projector Case
Before you clean the case, turn off the projector and unplug the power cord.
■To remove dirt or dust, wipe the case 
with a soft, dry, lint-free cloth.
■To remove stubborn dirt or stains, 
moisten a soft cloth with water and a 
neutral detergent. Then wipe the case 
and dry it with a dry cloth.
Caution: Never use wax, alcohol, benzene, 
thinner, or other chemical detergents. These 
can damage the case.
Cleaning and Replacing the Air Filter
Your projector includes an air filter to ensure the best performance. If dust collects on the air 
filter, clean it as described below. Dust clogs prevent proper ventilation and cause overheating 
and damage to the projector.
1. Press the Ppower button and wait for the Ppower light to stop flashing. The projector 
cools down.
2. Turn off the projector using the power switch on the back.
3. Unplug the power cord and disconnect any cables.
4. Turn the projector over (unless it’s ceiling mounted).
5. Push down on the tabs on the filter cover to remove it.
6. Remove the air filter as shown.
