Adjusting method:
1)
Select page: 0, address: 01, and set data: 01.
2) Select page: F, address: EA, set data: 76, and press the PAUSE
button of the adjustment remote commander.
3) Expose pattern A with the zoom TELE end.

of the waveform. (Oscilloscope is V period)
6) Select page: F, address: EA, set data: 8A, and press the PAUSE
button.
7) Measure the vertical position SV2 (msec) of the falling edge
of the waveform. (Oscilloscope is V period)
8) Obtain D
