*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.

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 adjusent 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 
adjusents. 
						

							Operation 42To adjust the settings:
1. Go to the PICTURE menu and select 3D Color Management.
2. Press MODE/ENTER and the 3D Color Management page displays.
3. Select Primary Color and press  /  to select a color from among Red, Yellow, 
Green, Cyan, Blue, or Magenta.
4. Press  to select 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 select Saturation and adjust its 
values to your preference by pressing  / . Every adjusent 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.
• 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 select Gain and adjust its values to your preference by pressing  / . 
The contrast level of the primary color you select will be affected. Every adjusent 
made will reflect to the image immediately.

SYSTEM 
SETUP: Basic > Operation 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.

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 ambient temperature is between 0°C–35°C. China 
region only applies at altitude up to 2000m.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient 
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 selected.
2. Press  to select High Altitude Mode and press  /  to select On. A 
confirmation message displays.
3. Select 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.
