ADJUSTMENT /
CONFIRMATION
6.8.1. V-CENTER ADJUSTMENT
1. Adjust V-POS (VGA) so that center of the crosshatch
pattern is center of the CRT.
6.8.2. V-HEIGHT ADJUSTMENT
1. Adjust V-AMP (VGA) so that A = B in Fig. 8.
6.8.3. H-CENTER ADJUSTMENT
1. Adjust H-POS (VGA) so that horizontal position is center of
CRT.
6.8.4. H-WIDTH ADJUSTMENT
1. Adjust H-AMP (VGA) so that C = D in Fig. 8.
6.9. VGA400 / 70 Hz DEFLECTION
ADJUSTMENT /
CONFIRMATION
6.9.1. V-CENTER ADJUSTMENT
1. Adjust V-POS (VGA 400) so that center of the crosshatch
pattern is center of the CRT.
6.9.2. V-HEIGHT ADJUSTMENT
1. Adjust V-AMP (VGA 400) so that A = B in Fig. 10.
2. Add 10 dac to the above data and set to EEPROM [336].
6.8.5. EW ADJUSTMENT
1. Adjust the vertical line to straight line by Parabola (VGA).
2. Adjust the vertical line to straight line of both side vertical
line in Fig. 9 by Trapezoid (VGA).
3. Confirm there is no H-Parallel distortion.
If there is distortion, adjust by H-Parallel (VGA).
In that case, repeat 2 and 3 so that there is no trapezoid /
parallel distortion.
4. Confirmation vertical pincushion of the corner side.
If needed, adjust Top-Corner (VGA) and Bottom-Corner

ADJUSTMENT
1. Confirm V-linear as to the balance of the circle.
If needed, adjust V-linear (VGA 400).
6.9.4. EW ADJUSTMENT
1. Confirm the vertical line is straight line.
If needed, adjust the vertical line to straight line by Parabola
(VGA 400).
2. Confirm both sides vertical line in Fig. 1 are straight line.
If needed, adjust the vertical line to straight line of both side
vertical line in Fig. 11 by Trapezoid (VGA 400).
3. Set H-SIZE in the user control to NORMAL.
(No need, if SELF CHECK is done before shipping).
