3. In case of Latin America model, Adjust deflection at N60Hz(NTSC)
Then, adjust deflection at 50hZ of PAL signal.
4. Store the deflection adjustment data in EEPROM by using
'ENTER' button.
After finishing deflection adjustment, press the 'EXIT' button to
exit from SVC mode.

PAL : Adjust upper and lower part of circle from the effective
screen of the CPT.to be distance of 6~7mm
1. V SLOPE
Half of the picture(bottom part) changed to blank.
Adjust so that half blanked- Picture bottom line in accord with
geometric vertical center of the CPT
2. V SHIFT(VS)
Adjust so that the horizontal center line of a digital circle pattern
is in accord with geometric horizontal center of the CPT.
3. V LINEAR(VL)
Adjust the top & bottom size of inner circle to be equal on EU05
CH and US13CH

NTSC : Adjust so that the circle of a digital circle pattern may
be located within the effective screen of the CPT.
5. H SHIFT(HS)
Adjust so that the Horizontal center line of a digital circle pattern
is in accord with geometric vertical center of the CPT.
6. EW WIDTH(EW)
Adjust outer line of the left/right outer lattice to be united with
effective boundary surface of CPT (Outer lattice: NTSC : 3.0 _
3.5 unit , PAL : 0~25% Range)
7. EW PARAB (EW PARABOLA)
Adjust so that middle portion of the outermost left and right
vertical line looks like parallel with vertical lines of the CPT.
8. EW TRAPE ( EW TRAPEZOID)
Make adjustment so that the top horizontal wideh and the
bottom horizontal width are equal.
(If screen is trapezoid, adjust to be square)
9. EW UPCOR & EW LOCORR
After completing the Cusion adjustment, make adjustments so
that the bottom left and right corner vertical Lines are straight.
10. H BOW
Adjust the left and right crooked line on upper and lower side.
11. H PARALL(ANGLE)
Adjust the vertical slope.
12. SCORRECT (S CORRECTION)
Adjust the lattice width of the Top/Center/Bottom to be the same.
