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-P4350,P3350,P3350B - 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.
