• 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, this is not processed as an error, and operation continues accordingly.
• If you design a new head unit, be sure to use one of the display formats indicated in “Display example of
the main unit.”
ERROR CODES
(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 main 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.
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.
• The 2 high-order digits of an error code denote the main
classification, shown below.
0x: Servo-related errors
1x: Servo-related errors
3x: Servo-related errors
5x: Mechanism-related errors
• How to restore from each error is shown below.
0x, 1x and 3x: ACC-OFF then ON, CD-OFF then ON,
Disc
ejection
5X: ACC-OFF then ON, Disc ejection, Disc reloading
