Procedure of Power Adjustment
Flow
1. DVD Power adjustment in the state where Focus is Closed.
2. DVD Power adjustment in the state where the setup is completed
3. CD Power adjustment in the state where Focus is Closed.
4. CD Power adjustment in the state where the setup is completed
Procedure of Adjustment
1. Set the mecha.
2. Turn on power.
3. Test Mode In.
4. Insert DVD GGV1025.
5. Set the mecha upside down.
6. Adjustment of the initial position of VR for Power adjustment.
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 Focus Close and Tracking Open (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 Mechanism Unit (Service).
11. Conduct Power adjustment. (Conduct the adjustment in the state of Focus Close.)
12. Execute until Tracking Close is reached.
13. Conduct Power adjustment. (Conduct the adjustment in the state of Tracking Close.)
14. Check the ERR rate after Power adjustment.
15. Power off.
16. Return to the original position.
17. Set up again (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.
Refer to FE test mode function flow.
