Procedure of Power Adjustment
Flow
1. DVD Power adjustment in the state where F is ON
2. DVD Power adjustment in the state where the setup is completed
3. CD Power adjustment in the state where F is ON
4. CD Power adjustment in the state where the setup is completed
Procedure of Adjustment
STEP No.
1. Set the mecha to clockwise.
2. Turn on power.
3. Test Mode In
4. Insert DVD TDV-582 (or TDV-520).
5. Set the mecha to counterclockwise.
6. Adjustment of the initial position of VR for Power adjustment
CD (VR1101)
DVD (VR1102)
7. Set DISC TYPE to DVD single layer.
8. Power on.
9. LD-ON
10. Execute until Focus close state 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 9.
If the RF waveform does not appear, Focus Close is not reached.
Return to STEP 7 and change the angle of initial position of DVD VR (VR 1102). 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.
DVD 200 mV to 1200 mV
11. Conduct Power adjustment. (Conduct the adjustment in the state of Focus Close.)
DVD 848 mV to 892 mV
12. Execute until Tracking Close is reached.
13. Conduct Power adjustment. (Conduct the adjustment in the state of Tracking Close.)
DVD 2.0E – 4 and under
14. Check the ERR rate after Power adjustment.
DVD 820 mV to 917 mV
DVD 2.0E – 4 and under
15. Power off.
16. Return the state of mecha to clockwise.
17. Set up again (state of mecha to clockwise / setting of DVD single layer) and conduct the final check of RF level and ERR rate.
(Check in the state of Tracking Close)
18. Eject.
