(6) EW WIDTH
Adjust until the outmost left and right lattice of received
pattern is accord with 25% of other lattice width.
<Fig. 2>PAL Digital pattern (EU05CH)
(7) EW PARABOLA
Adjust so that middle portion of the outermost left and right
vertical line look like parallel with vertical lines of the CPT.
(8) EW UPCORNER & (9) EW LOCORNER
After finished cushion adjustment, adjust vertical line of left-
top, right-top, left-bottom, right-bottom of screen to the best
straight line.
