2-2-2(b) SKEW Adjustment Method
Needed to minimize the variations in Skew of the Pick-up unit and to provide optimum match with the recorded
signal on the Disc.
1) Remove the Ass’y Deck.
Place the Ass’y Deck on a flat horizontal position.
2) Connect an Oscilloscope to the “ENV” Test Point. (See Fig. 2-5)
◆
Set the Oscilloscope Range as follows :
(Voltage ; 50mV/Div., Frequency ; 10m Sec.)
3) Connect Power, Open the Tray and Play the TDV-533 Disc, Chapter 14.
4) Adjust the Screws “A” and “B” (See Fig. 2-6) using a Hex screwdirvier until you obtain a Flat Waveform and
the picture is stable.
Then, go to Chapter 1 and make sure the Waveform is Flat here as well.
If not, you have to go back to Chapter 14 and adjust again.
If you cannot obtain a Flat waveform, then the unit is defective.
Note : The Deck must be in a horizontal position. Use both “A” and “B” screws to adjust, but mostly “A”.
