3.5.5 Red/Green Formatter Convergence Adjustment Description

The Red and Green Formatters are identical in physical layout and adjuster function. The vertical and twist
adjustments interact with each other on the horizontal axis, as described in Figure 3-13.
The physical layout of the Red/Green Formatter boards dictates the behavior of the Twist and Vertical
adjustments:
• The adjustment of the two is more like a "Twist with the left-side of the screen as a sliding hinge point to
allow vertical travel"
• The vertical adjustment screw and twist adjustment screw interact with each other such that if one is turned
in the opposite direction of the other, the twist is affected.
• If both screws are turned equal amounts in the same direction, the image moves vertically.
You do not always have to turn the screws simultaneously; however, adjusting one at a time will cause the need
for an equal or equal and opposite turn on the other to prevent binding and achieve the adjustment desired.
