-- Low fix (No Connection.) Output terminal for switching the capstan voltage. [Other than PLAY/REC mode]...............Always "High". [JOG/Shuttle mode in PLAY mode ]......Always "High". O After 5 seconds from PLAY/REC mode completion, it changes to "Low". During "Low" outputs, it checks every main capstan FG, when the no FG is inputted in a rotation, it changes to "High" and it keeps "high" by cassette ejection. Output terminal for V_sync detection result. [Vsync exist] : "Low" [Vsync not exist: "High"
