Others: Preset
(1) Input a 50Hz composite sync signal into Pin61.
(2) Set V-Freq to 0.
(3) For no input, measure the frequency of V Ramp at Pin46,
that is "FVAUFR50".
(4) Input a 60Hz composite sync signal into Pin61.
(5) Repeat (2)&(3), that is “FVAUFR60”
(6) Set V-Freq. To 1/2, repeat (2), that is "FV50FR" / "FV60FR".
