N OTE : Moire is an interface pattern that makes the screen seem to have faint lines. A picture
that is rastered or consists of small repeating figures is sensitive to moire interference.
Strong colors are also liable to intensify moire. The moire pattern on the screen does not
affect the printout of the image.
Degauss
External magnetic fields may cause distortion or discoloration
in the picture. Demagnetizing takes place automatically when
the display unit is switched on, and the unit normally maintains
faultless color purity during operation.
If you have tilted, swiveled or moved the display unit, you can
perform demagnetization. During the process the picture is
distorted for a few seconds. After demagnetization, the color
impurities have disappeared if caused by stray magnetic fields.
Do not use the degauss feature more than once every half hour
or the degauss function will not work.
Brightness Adjusts the brightness of the screen.
Contrast Adjusts the contrast of the screen.
