CD ADJUSTMENTS
CD PLAYER ADJUSTMENT PROCEDURES
Adjusting Conditions:
- Test disc: Sony YEDS-18
- Pre-operating : Push open/close key to open the CD tray.
Load test disc YEDS-18, then push this key once against to close tray.
- Oscilloscope:
1) Adjustment of E/F balance
- After TOC. push play/pause key once to play and push SEARCH key to search.
- Connect the scope between the measurement points.(TSO , V-CEN)
- Then adjust the VR701 until A=B( as figure A)
2) Adjustment of RF (EYE PATTERN)
Figure A
- After TOC. push play/pause key once play.
- Connect the scope and Jitter meter between the measurement points (RF , V-CEN)
