Remarks
Errors are not displayed for the individual mecha unit (since CD is turned off at mecha error).
When TOC cannot be read, it is not recognized as an error but the operation is continued accordingly.
When designing a new head unit, be sure to follow the display examples.
The higher digit of error codes indicates a major category as shown below.
Code Category
1x Servo-related errors
2x TOC lead-related
3x Servo-related errors
5x Mecha-related errors
The following shows how to recover from each error.
Servo-related errors (1x, 2x, 3x):
Loading-related and ejection-related errors (50, 52):
Ejection rotation retrial errors (51): CD ON, EJECT, ACC OFF, Back-up OFF, COMMUNICATION RESET, RESET
