							Operation 31 6. Press  to select a menu item to be changed and adjust the value with /. See 
Fine-tuning the image quality in user modes below for details.
7. When all settings have been done, highlight Save Settings and press MODE/
ENTER to store the settings.
8. The confirmation message “Setting Saved” is displayed.
Fine-tuning the image quality in user modes
According to the detected signal type, there are some user-definable functions available 
when User 1 or User 2 is selected. Based on your needs, you can make adjustments to 
these functions by highlighting them and pressing  /  on the projector or remote 
control.
Adjusting Brightness
The higher the value, the brighter the image. And the 
lower the setting, the darker the image. Adjust this 
control so the black areas of the image appear just as 
black and that detail in the dark areas is visible.
Adjusting Contrast
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.
Adjusting Color
Lower setting produces less saturated colors. If the setting is too high, colors on the image 
will be overpowering, which makes the image unrealistic.
Adjusting Tint
The higher the value, the more reddish the picture becomes. The lower the value, the 
more greenish the picture becomes.
Adjusting Sharpness
The higher the value, the sharper the picture becomes. The lower the value, the softer the 
picture becomes.
Adjusting Brilliant Color
This feature utilizes a new color-processing algorithm and system level enhancements to 
enable higher brightness while providing truer, more vibrant colors in picture. It enables a 
greater than 50% brightness increase in mid-tone images, which are common in video and 
natural scenes, so the projector reproduces images in realistic and true colors. If you 
prefer images with that quality, select On. If you don’t need it, select Off.
When Off is selected, the Color Temperature function is not available.
Selecting a color temperature
The options available for color temperature* settings vary according to the signal type 
selected.
1.Cool: Makes images appear bluish white.
2.Normal: Maintains normal colorings for white.
3.Warm: Makes images appear reddish white.

							Operation 32There 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.
3D Color Management
In most installation situations, color management will not be necessary, such as in 
classroom, meeting room, or lounge room situations where lights remain on, or where 
building external windows allow daylight into the room. 
Only in permanent installations with controlled lighting levels such as boardrooms, lecture 
theaters, or home theaters, should color management be considered. Color management 
provides fine color control adjustment to allow for more accurate color reproduction, 
should you require it.
Proper color management can only be achieved under controlled and reproducible viewing 
conditions. You will need to use a colorimeter (color light meter), and provide a set of 
suitable source images to measure color reproduction. These tools are not provided with 
the projector, however, your projector supplier should be able to provide you with suitable 
guidance, or even an experienced professional installer.
The Color Management provides six sets (RGBCMY) of colors to be adjusted. When you 
select each color, you can independently adjust its range and saturation according to your 
preference.
If you have purchased a test disc which contains various color test patterns and can be 
used to test the color presentation on monitors, TVs, projectors, etc, you can project any 
image from the disc on the screen and enter the 3D Color Management menu to make 
adjustments.
To adjust the settings:
1. Go to the PICTURE menu and highlight 3D Color Management.
2. Press MODE/ENTER on the projector or remote control and the 3D Color 
Management page is displayed.
3. Highlight Primary Color and press  /  to select a color from among Red, 
Yellow, Green, Cyan, Blue, or Magenta.
4. Press  to highlight Hue and press  /  to select its range. Increase in the range 
will include colors consisted of more proportions of its two adjacent colors.
Please refer to the illustration to the right 
for how the colors relate to each other.
For example, if you select Red and set its 
range at 0, only pure red in the projected 
picture will be selected. Increasing its range 
will include red close to yellow and red close 
to magenta.
5. Press  to highlight Saturation and adjust 
its values to your preference by pressing  /
. Every adjustment made will reflect to 
the image immediately.
For example, if you select Red and set its 
value at 0, only the saturation of pure red will be affected.

							Operation 33
Saturation is the amount of that color in a video picture. Lower settings produce less saturated colors; a 
setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be 
overpowering and unrealistic.
6. Press  to highlight Gain and adjust its values to your preference by pressing  /
. The contrast level of the primary color you select will be affected. Every 
adjustment made will reflect to the image immediately. 
7. Repeat steps 3 to 6 for other color adjustments.
8. Make sure you have made all of the desired adjustments.
9. Press MENU/EXIT to exit and save the settings.

Remote paging operations
Connect the projector to your PC or notebook with a USB cable prior to using the paging 
function. See Connection on page 17 for details.
You can operate your display software program (on a connected PC) which responds to 
page up/down commands (like Microsoft PowerPoint) by pressing PAGE UP/PAGE 
DOWN on the remote control.
If remote paging function doesnt work, check if the USB connection is correctly made and 
the mouse driver on your computer is updated to the latest version.
The remote paging function cannot work with Microsoft® Windows®98 operating system. Windows®XP or 
higher operating systems are recommended.
Freezing the image
Press FREEZE on the remote control to freeze the image. The word “FREEZE” will be 
displayed in the upper left corner of the screen. To release the function, press any key on 
the projector or remote control.

LASER, #1, #4, PAGE UP/PAGE DOWN.
Even if an image is frozen on the screen, the pictures are running on the video or other 
device. If the connected devices have active audio output, you will still hear the audio even 
though the image is frozen onscreen.
Hiding the image
In order to draw the audiences full attention to the presenter, you can use ECO BLANK 
on the projector or remote control to hide the screen image. The word “ECO BLANK” 
appears in the corner of the screen while the image is hidden. When this function is 
activated with an audio input connected, the audio can still be heard.
