4. By rotating the Yoke, visually adjust the Blue horizontal Skew
at the center portion of the screen (the upper and lower por-
tions may not be properly aligned).
5. Re-tighten the Yoke clamp.
6. Remove ONLY the lower Setup Pin Jumper, enabling the
Convergence Panel Controls. Do not remove the other
jumpers at this time (keep Customer Controls disabled).

etc.) on the Convergence Panel. Refer to the Convergence
Board Control Layout And Alignment Guide (included in your

convergence.
