							Operation 41 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 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. 
6. 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.
7. Repeat steps 3 to 6 for other color adjusents.
8. Make sure you have made all of the desired adjusents.
9. Press MENU on the projector or remote control to exit and save the settings.

Hiding the image
Press the ECO BLANK button from remote control to 
turn off the image for a period of time with up to 70% 
lamp power saving. Press any key on the projector or 
remote control to restore the image.
The word Eco Blank appears at the screen while the 
image is hidden. When this function is activated with an 
audio input connected,the audio can still be heard.
‘Eco Blank: Save up 70% of your lamp power. 
Time to do your part in saving the planet.’
The automatic switch to Eco Blank mode after the 
projector is turned on for over three minutes without a display source, eliminating 
unnecessary energy waste and prolonging the life of the projector lamp.
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. 
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. Open the OSD menu and make sure the Menu Type is Advanced.
2. Go to the System Setup: Advanced > High Altitude Mode and press  /
 to select On. A confirmation message displays..
3. Select Ye s and press OK 
on the projector or remote control.
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.
