(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.

(10) EW TRAPEZOID
Adjust to make the length of top horizontal line same with it
of the bottom horizontal line.
(11) V SLOPE
(12) V AMPLITITUE
Adjust so that the circle of a digital circle pattern should be
located interval of 6~7mm from the effective screen of the
CPT.
(13) S CORRECTION
Adjust so that all distance between each lattice width of
top/center/bottom are to be the same.
(14) V SHIFT
Adjust so that the geometric vertical center line is in accord
with vertical center line of CPT.
(15) V ZOOM (VERTICAL ZOOM)
(16) PIP_H(PIP H Position) adjustment - option
Adjust the H-Position by using VOL +/- key until PIP picture
is in contact with main picture.

- After finishing deflection adjustment at PAL 50Hz, NTSC 60Hz
is applied deflection compensation value. But recheck condition
of adjustment at NTSC system and adjust deflection data if
necessary.
- Adjust PIP Position adjustment at only PAL 50Hz.
