  • Page 41: Adjustment

    6. ADJUSTMENT 6.1 CD ADJUSTMENT 1) Precautions • This unit uses a single power supply (+5V) for the reg- ulator. The signal reference potential, therefore, is connected to REFO(approx. 2.5V) instead of GND. If REFO and GND are connected to each other by mis- take during adjustments, not only will it be impossi- ble to measure the potential correctly, but the servo will malfunction and a severe shock will be applied to...

    6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT • Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mecha- nism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module.

    7. GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 TEST MODE - Error Messages If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the users and also for facilitating trouble analysis and repair work in servicing.
  • Page 46 DEH-2130R,2100R - New Test Mode S-CD plays the same way as before. If an error such as off focus, spindle unlocking, unreadable sub-code, or sound skipping occurs after setup, its cause and time occurred (in absolute time) are displayed. During setup, operational status of the control software (internal RAM: CPOINT) is displayed. These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.
  • Page 47 (4) Display of Operational Status (CPOINT) during Setup Status No. Contents Carriage move to home position started. Carriage is moving toward inner diameter. Carriage is moving toward outer diameter. Carriage outer diameter feed (1 second) in progress. Setup started. Spindle rotation and focus search started. Waiting for focus close (XSI Low).
