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
(minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO
remains in blank as before.
2) Main 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
OR
Err–xx
