This arrangement is intended at reducing nonsense calls from the users and also for facilitating trouble analysis and repair work in servicing.
  • Page 51 DEH-P7300R,P6300R - 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 is displayed. These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.
