5.2 ERROR CODE LIST
ERROR CODES
If a CD memory device is inoperable, or operation of such media is stopped by an error, the error mode is established and a
cause of the error is displayed by an error code. Indication of error codes is intended to reduce the number of calls from
customers and facilitate failure analysis and repair work in servicing.
(1) DISPLAY METHOD
If "0xFD" error mode is displayed in CD MODE (CD MODE area for display), an error code will be displayed in the MIN (minute
display) and SEC (second display) areas.
The same code is displayed in the MIN and SEC areas.
The TNO area is blank (#0FFH), as it conventionally was.
• Display example of the head unit
Depending on the display capability of LCDs, the display format varies, as shown below. XX denotes an error number.
Note: In a case of an OEM product, the error display format is subject to the specifications used by the equipment
manufacturer.

NOTES
• Indications of error codes are available only during disc operations, because CD operations are unavailable if a mechanical error is
generated.
• If the TOC cannot be read, It stops because of error 07.
• If you design a new head unit, be sure to use one of the display formats indicated in "Display example of the head unit."
• The 2 high-order digits of an error code denote the main classification, shown below.
