of usage. The Color Return feature allows you to help restore the color to the original fac-
tory preset levels.
MOIRE ADJUST - Adjusting the moire
Moire is a type of natural interference which produces soft, wavy lines on your screen. It
may appear due to interference between the pattern of the picture on the screen and the

A white rectangle appears in the center of the screen
while the image is being restored (about two seconds).
