11.4. Error Code Table
11.4.1. Error code for Power Supply
Error Code Abnormal Items Possible Cause
F61 POWER AMP output
abnormal During normal operation, if either DCDET1 or DCDET2 becomes L, normal POWER OFF
process shall not be executed, PCNT shall be switched to L immediately. GOODBYE shall not
display and the error display F61 is displayed instead. 2 seconds after the F61 display, ECONO
shall be set to ´L´ and LCD display shall be turned off. The error content shall be memorised
when the abnormality occurs and can be display in the C-mecha self-diagnostic mode described
later.
11.4.2. Error codes for CD Mechanism
Error Code Abnormal Items Possible Cause
F15 CD REST SW abnormal CD traverse position intial setting operation failsafe counter (1000 ms) waiting for REST SW to
turn on. Error No. shall be clear by force or during coldstart.
F26 CD servo LSI command
signal abnormal CD function DTMS command, after system setting, If SENSE = ‘L’ cannot be detected.
Memory shall contain F26 code. After Power on, CD function shall continue, error shall occur
“NO DISC”.
Error No. shall be clear by force or coldstart.
F28 DISC LOAD abnormal While going to play position, if failsafe counter is finished and switch o change or switch
target condition was not achieve, this error shall be memorized. Next time mechanism
operates, it shall do coldstart.
Error No. shall be clear by force or coldstart.
F29 DISC unload abnormal While going to play position, if failsafe counter is finished and switch no change or switch
target condition was not achieve, this error shall be memorized. Next time mechanism
operates, it shall do coldstart.
Error No. shall be clear by force or coldstart.
F27 Slide operation abnormal During vertical operation, if failsafe timer is finished and switch no change or switch target
condition was not achieve, this error shall be memorized. Next time mechanism operates, it
shall do coldstart.Error No. shall be clear by force or coldstart.
F17 Down SW abnormal During vertical operation going to the bottom position, if failsafe timer is finished and switch
no change or switch target condition was not achieve, this error shall be memorized. The
Next time mechanism operates, it shall do mechanism initialization.Error No. shall be clear by
force or coldstart.
F22 Loading Mode / Mecha
abnormal During mecha initialization, Loading mode mechanism abnormal, normal operation cannot be
achieve. The next time mechanism operates, it shall do mechanism initialization.Error No.
shall be clear by force or coldstart.
11.4.3. Error codes for Cassette Mechanism

H01 MODE SW abnormal Normal operation during mecha transition, MODE SW abnormal is memorised. The content
of abnormality can be confirmed in the abnormal detection mode explained in the later
section.
H02 REC INH SW abnormal
The content of abnormality can be confirmed in the abnormal detection mode explained in
the later section.
H03 HALF SW abnormal
F01 Reel pulse abnormal
F02 TPS abnormal
11.5. Cassette Mechanism Self-Diagnostic Mode
1. A Cr02-positioned blank cassette tape with an erase prevention niche on either Side A or B.
2. A normal-positioned music tape with erase prevention niches on both Sides A and B. Both tapes are halfway forwarded in
advance.
3. The remote controller that comes with this unit.
