"ADJUST"

The first 3 adjustments (horizontal red, green, blue) are used for horizontal light equalisation for the three specific colors separately. This
compensates the error due to the different horizontal positions of the picture tubes. One side of the image is reddish and the other side is
blueish. This phenomenon is called
Color shift
.
The
VERTICAL
adjustment affects the three colors at the same time
and corrects the vertical error in light output due to the projection angle
(10.5 degrees).
Left and right (horizontally) and top and bottom (vertically) adjust-
ments improves the '
hot spot
' in the center of the screen.
Notes:
- An external generated white image will be useful during the
following adjustments.
- Be sure the horizontal phase is correctly adjusted. The image must
be centered on the raster with the horizontal phase adjustment,
otherwise it is not possible to adjust the contrast modulation
correctly.

Highlight
RED HORIZONTAL
with the arrow keys and press
"EN-
TER"
.
Only a red image is displayed. Use the arrow keys to equalise the light
output on the left and right side of the image. The best result is obtained
by looking on the left and the right side until both are equal, or by using
a very sensitive light meter.
"ENTER"
returns to the contrast modulation menu.
Repeat this adjustment for green and blue by selecting first Green
horizontal and than Blue horizontal.
Note:
(only for non-ASIC controllers) When the end of adjustment
range is reached for red and blue, the green image will also be
displayed, to give you the message "end of adjustment range". The
green image stays active until a new selection is made.
