(1) Input vertical trigger pulse to pin V
(2) Apply external power supply V
(3) Set EW PARABOLA (sub-address: 0A) to center (data: 20).
(4) Set external power supply V
(5) Set external power supply V
(6) Calculate change amount EHT using the following formula.
(1) Input vertical trigger pulse to pin V
(2) When V AGC (sub-address: 09) is switched, set data to 00, 40, 80, and C0 and
(3) Connect GND through 200 Ω to pin 24 (AGC FILTER).
