If the effective voltages cannot be completely corrected by signals C1 and C2 which are generated by
comparators, the IC2 amplifies the voltages. The amplification with the multivibrator makes the pulse
widths constant and noise that fluctuates depending on display patterns cannot be corrected. Therefore, IC2
outputs are ORed with signals C1 and C2. The pulse widths or CC1 and CC2 are optimized by correcting
the C3, C4, R3, and R4 values while monitoring the display screen.

The pulse widths of CC3 and CC4 are amplified with the multivibrator (LS123) at the falling edge of CL1.
The pulse widths of CC3 and CC4 are optimized by correcting the C5, C6, R5, and R6 values while
monitoring the display screen.
