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.Cooler: makes the image appear bluish white.
2.Normal: Maintains normal colorings for white.
3.Wa r m : 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.
Setting a preferred color temperature
To set a preferred color temperature:
1. Highlight Color Temperature and select Wa r m, Normal or Cool 
by pressing ◄/► on the projector or remote control.
2. Press ▼ to highlight Color Temperature Fine Tuning and press 
MODE/ENTER. The Color Temperature Fine Tuning page appears.
3. Press ▲/▼ to highlight the item you want to change and adjust the 
values by pressing ◄/►.
•R Gain/G Gain/B Gain: Adjusts the contrast levels of Red, 
Green, and Blue.

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 and the 3D Color Management page displays.
3. Highlight Primary color and press ◄/► to select a color from among 
Red, Green, Blue, Cyan, Magenta and Yellow.
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.
RED
BLUEGREEN Yellow
Cyan
Magenta 
						

							Operation43
For example, if you select Red and set its value at 0, only the saturation 
of pure red will be affected.
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 25 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 PA G E  + / PA G E  - 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 appear on the screen. To release the function, press any key 
on the projector or remote control.
If your remote control has the following keys, please note that they cannot 
be pressed to release the function: LASER, #2, #5, PA G E  + / PA G E  -.
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 on screen.
Hiding the image
In order to draw the audiences full attention to the presenter, you can use 
ECO BLANK on the remote control to hide the screen image. When the 
function is activated with an audio input connected, the audio can still heard.
You can set the blank time in the 
System Setup: Basic > Operating Settings 
> Blank Timer 
menu to let the projector return the image automatically after 
a period of time when there is no action taken on the blank screen. The 
length of time can be set from 5 to 30 minutes in 5-minute increments.
If the preset time spans are not suitable for your presentation, select 
Disable.
No matter 
Blank Timer is activated or disabled, you can press most of the 
keys on the projector or remote control to restore the picture.
•  Do not block the projection lens from projecting as this could cause the 
blocking object to become heated and deformed or even cause a fire. 
						

							Operation 46
Locking control keys
With the control keys on the projector locked, you can prevent your 
projector settings from being changed accidentally (by children, for example). 
When the Panel Key Lock is on, no control keys on the projector will 
operate except   POWER.
1. Go to the System Setup: Basic > Panel Key Lock menu, and select 
On by pressing ◄/► on the projector or remote control. A 
confirmation message appears.
2. Highlight Ye s and press MODE/ENTER to confirm.

Operating in a high altitude environment
We recommend you use the High Altitude Mode when your environment 
is between 
1500 m –3000 m above sea level, and temperature is between 0°C–30°C.
Do not use the High Altitude Mode if your altitude is between 0 m and 
1500 m and temperature is between 0°C and 35°C. The projector will be 
over cooled, if you turn the mode on under such a condition.
To activate the High Altitude Mode:
1. Press MENU/EXIT and then press ◄/► until the System Setup: 
Advanced menu is highlighted.
2. Press ▼ to highlight High Altitude Mode and press ◄/► to select 
On. A confirmation message displays.
3. Highlight Yes and press MODE/ENTER.
Operation under High Altitude Mode may cause a higher decibel 
operating noise level because of increased fan speed necessary to improve 
overall system cooling and performance.
If you use this projector under other extreme conditions excluding the 
above, it may display auto shut-down symptoms, which is designed to protect 
your projector from over-heating. In cases like this, you should switch to 
High Altitude mode to solve these symptoms. However, this is not to state 
that this projector can operate under any and all harsh or extreme 
conditions.
