6.3 ERROR 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.

(1) Basic Indication Method

1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (min-

utes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains

in blank as before.

2) Head unit display examples

Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

8-digit display 6-digit display 4-digit display

ERROR–xx ERR–xx E–xx

(2) Error Code List

Code Class Displayed error code Description of the code and potential cause(s)

10 Electricity Carriage Home NG CRG can't be moved to inner diameter.

SERVO LSI Com- CRG can't be moved from inner diameter.

munication Error → Failure on home switch or CRG move mechanism.

Communication error between microcomputer and SERVO LSI.

11 Electricity Focus Servo NG Focusing not available.

→ Stains on rear side of disc or excessive vibrations on REWRITABLE.

12 Electricity Spindle Lock NG Spindle not locked. Sub-code is strange (not readable).

Subcode NG → Failure on spindle, stains or damages on disc, or excessive vibrations.

A disc not containing CD-R data is found.

Turned over disc are found, though rarely.

CD signal error.

17 Electricity Setup NG AGC protection doesn't work. Focus can be easily lost.

→ Damages or stains on disc, or excessive vibrations on REWRITABLE.

30 Electricity Search Time Out Failed to reach target address.

→ CRG tracking error or damages on disc.

44 Electricity ALL Skip Skip setting for all track.

(CD-R/RW)

50 Mechanism CD On Mech Error Mechanical error during CD ON.

→ Defective loading motor, mechanical lock and mechanical sensor.

A0 System Power Supply NG Power (VD) is ground faulted.

→ Failure on SW transistor or power supply (failure on connector).

Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).

Unreadable TOC does not constitute an error. An intended operation continues in this case.

Upper digits of an error code are subdivided as shown below:

1x: Setup relevant errors, 3x: Search relevant errors, Ax: Other errors.
