1. Load a program, and turn on both the computer and
the monitor.
2. Turn the contrast control up as high as it will go.
(Rotate the knob away from you.)
3. Turn the brightness control clockwise until the
background lines on the screen are clearly visible.
4. Turn the brightness control counterclockwise until the
background lines just disappear.
5. Adjust the contrast control to give a pleasing level of
text illumination.
