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).
C
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.)
