Color Temp 
(depends on 
the selected 
Application 
mode)
There are 4 color temperature* settings available.
This value will be reset if you subsequently select an Application 
mode
1.T1: With the highest color temperature, T1 makes the image 
appear the most bluish white than other settings.
2.T2: Makes images appear bluish white.
3.T3: Maintains normal colorings for white.
4.T4: Makes images appear reddish white.
*About color temperatures:
There are many different shades that are considered to be “white” for 
various purposes. One of the common methods of representing white 
color is known as the “color temperature”. A white color with a low color 
temperature appears to be reddish white. A white color with a high color 
temperature appears to have more blue in it.
Brightness 
(depends on 
the selected 
Application 
mode)
Adjusts the brightness of the image. The higher the value, the brighter the 
image. And lower the value, the darker the image. Adjust this control so 
the black areas of the image appear as black and that detail in the dark 
areas is visible.
Contrast 
(depends on 
the selected 
Application 
mode)
Adjusts the degree of difference between dark and light in the image. The 
higher the value, the greater the contrast. Use this to set the peak white 
level after you have previously adjusted the Brightness setting to suit 
your selected input and viewing environment.
Color 
(depends on 
the selected 
input source)Increases or decreases the color intensity of the image.
Tint (50)
Adjusts the color tones of the image. The higher the value, the more 
greenish the image becomes. The lower the value, the more reddish the 
image becomes.
When a Video or S-Video signal is connected, the function is only 
available with NTSC system selected.

Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you need to do on a regular basis is 
to keep the lens clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other parts 
need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
• Use a canister of compressed air to remove dust. 
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens 
cleaner and gently wipe the lens surface.
Never rub the lens with abrasive materials.
Cleaning the projector case
Before you clean the case, turn the projector off using the proper shutdown procedure as 
described in Shutdown on page 28 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 pH 
detergent. Then wipe the case.
• Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage 
the case.
• Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when 
cleaning the projector body and lens. Flammable substances may ignite causing fire or 
breakdown while the lamp is illuminating.
Storing the projector
If you need to store the projector for an extended time, please follow the instructions below:
• Make sure the temperature and humidity of the storage area are within the 
recommended range for the projector. Please refer to Specifications on page 46 or 
consult your dealer about the range.
• Retract the adjuster feet.
• Remove the battery from the remote control.
• Pack the projector in its original packing or equivalent.
Transporting the projector
It is recommended that you ship the projector with its original packing or equivalent. When 
you carry the projector yourself, please use the original box or provided soft carry case. 
						

							EN-39
ENGLISH
Calculation of lamp hour
When the projector is in operation, the duration (by hours) of lamp usage is automatically 
calculated by the built-in timer. The method of calculating the equivalent lamp hour is as 
follows:
Total (equivalent) lamp hour = hours used in Economic mode + hours used in normal mode
See Economic Mode (Off) on page 36 for more information on Economic mode.
The lamp hour in Economic mode is calculated as 2/3 of that in normal mode. That is, using 
the projector in Economic mode helps to extend the lamp hour by 1/3.
Warning message
When the LAMP indicator lights up red or a message appears suggesting it is time to 
replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a 
malfunction in the projector and in some instances the lamp may explode.
For more detailed information on projector warnings, please refer toIllustration on page 
42.
The LAMP indicator light and TEMP (Temperature) warning light will light up if the lamp 
becomes too hot. Turn the power off and let the projector cool for 45 minutes. If the LAMP or 
TEMP indicator still lights up after turning the power back on, please contact your dealer.
The following Lamp warning displays will remind you to change the lamp.
