tune the horizontal angle.
To retract the foot, hold up the projector while pressing the front adjuster button, then 
slowly lower the projector. Screw the rear adjuster foot in a reverse direction.
If the screen and the projector are not perpendicular to each other, the projected image 
becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the 
Picture menu, on the projector control panel, or on the remote control. Refer to Correcting 
keystone on page 28 for details.

application modes so that you can choose one to suit 
your operating environment and input source picture 
type. To select a operation mode that suits your need, 
press Mode. The picture modes available for different 
types of signals are shown below. See Application 
Mode on page 33 for details.
Switching input signal
The projector can be connected to multiple devices

and properly calibrated camera, and for viewing PC graphic and 
drawing applications such as AutoCAD.
4.Gaming Mode: Is suitable for playing PC-based games in a bright 
living room.
5.Video Mode: Is appropriate for playing movies, video clips from 
digital cameras or DVs through the PC input for best viewing in a 
blackened (little light) environment.

page 28 for more information. 
						

							Operation 34
Color Temp 
(depends on 
the selected 
Application 
mode)
There are four color temperature* settings are available.
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 
input source)
Adjusts the brightness of the image. The higher the value, the brighter 
the image. And lower the setting, 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. 
Contrast 
(depends on 
the selected 
input source)
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.
