(3) VL (Vertical Linearity)
Adjust so that the boundary line between upper and lower
half is in accord with geometric horizontal center of the
CPT(PAL : E5ch., NTSC : US-13.).
(4) VA (Vertical Amplitude)
Adjust so that the circle of a digital circle pattern may be
located within the effective screen of the CPT.

NTSC signal : Adjust NTSC 13CH circle as an inscribed
circle of vertical outer boundary of the effective screen of
the CPT.
(5) HS (Horizontal Shift)
Adjust so that the vertical center line of a digital circle
pattern is in accord with geometric vertical center of the
CPT
?@@? ?@@?
(6) EW (Horizontal Width)
Adjust to that a digital circle pattern looks like exact
circle.(PAL:0~25%,NTSC: 2.5~3.0)
(7) EP (East-west Parabolar)
Adjust so that middle portion of the outermost left and right
vertical line looks like parallel with vertical lines of the CPT.
(8) ET (East-west Trapezium)
Adjust to make the length of top horizontal line same with it
of the bottom horizontal line.
(9) EW UPCOR & EW LOCOR
Adjust until symmetrize upper&lower coner of the screen.
(10) BOW
Adjust the left and right crooked line on upper and lower
side.
(11) H ANGLE
Adjust the vertical slope
(12) S CORRECT (S CORRECTION)
Adjust the receive Patter, keep the lattice's range
same(Top/Center/Bottom)

This decided by DY data,so according to the CPT's Default
data(Initial data) Setting.
(13) V SCROLL
Adjust the center vertical line of the geometrical with the
CPT center vertical line same.
(14) V ZOOM (fixed) : VERTICAL ZOOM.
(15) WBR (fixed) : Timing of wide Blanking
(16) WBF (fixed) : Timing of wide Blanking

After PAL50Hz adjustment for Pal mode,NTSC60Hz apply
deflection redress data,but you need confirm the
adjustment condition in NTSC System again,if it is no
good,you need readjust it in NTSC mode.
