19. Take out DVD TDV-582 (or TDV-520).
Insert CD TCD-782 (or TCD-792).
20. Set the mecha counterclockwise.
21. Adjustment of the initial position of VR for Power adjustment
22. Set DISC TYPE to CD.
23. Power on.
24. Execute until Focus Close 1 is reached.
If the waveform is similar to RF waveform after F-ON and before T-ON (waveform measured by analog oscilloscope), Focus Close is reached.
Go to STEP 20.
If the RF waveform does not appear, Focus Close is not reached. Return to STEP 21 and change the angle of initial position of CD VR (VR1101).
If Focus Close is not reached after the 3rd VR adjustment, replace the whole CRG mecha (including PU unit) and start again from STEP 1.
25. Conduct Power adjustment. (Conduct the adjustment in the state of Focus Close.)
26. Execute until Tracking Close is reached.
27. Conduct Power adjustment. (Conduct the adjustment in the state of Focus Close.)
28. Check ERR rate.
29. Power off.
30. Return the state of mecha to clockwise.
31. Set up again (state of mecha to clockwise / setting of CD layer), and conduct the final check of RF level and ERR rate.
(Check in the state of Tracking Close)
32. Eject.
33. Take out CD TCD-782 (or TCD-792).
34. Power off.
Adjust the angle at the D cut position to the initial position
(initial position shown in Fig.2).
