Error Number Indication
The system enters error mode to display the cause of error with a number when the system cannot operate CD or
stops operation because of an error. The purpose of this measure is to reduce frequency of calls from users asking
help for problems that are caused by incorrect operation by user, as well as to assist analysis and repair in servicing.
(1) Basic means of display
• An error code will be written on DMIN (minute area for display) and DSEC (second area for display) when CSMOD
(CD mode area for system) is SERBORM.
The same data will be written on DMIN and DSEC.
DTNO shall be blank as before.
• Display examples of the head unit
Error codes will be displayed as shown below, depending on the capability of LCD. An error number will be dis-
played in the place of "xx."
•8-digit display
ERROR-XX
•6-digit display
ERR-XX or Err-XX
•4-digit display
E-XX
With OEM products, display of error codes shall be according to the specificatins of the manufacturer.

4) Number of error codes
One hundred error codes (00 to 99) will be available.
(5) Remarks
•Error codes are not displayed for the mechanism alone (because CD is OFF when an mechanical error is
generated).
•When the system cannot read TOC, it is not deemed as an error, and the system continues operation to a
certain extent.
•Be sure to take measures as shown in the display examples whenever designing a new head unit.
•The first digit of an error code has a meaning as follows:
1X : Error related to setup
3X : Error related to the search function
AX : Other errors
