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.
No.
1 C-mecha Abnormal Detection shall be
executed for DECK 1 only.
2 [ ] key is pressed, after loading in a
NORMAL type cassette with the recording tab
on the left side removed.
3 [ ] key is pressed, after loading a NORMAL,
CrO2, METAL type cassette with the recording
tab on the right side removed.
Abnormal Items
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.
Abnormal Items
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.
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.
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.
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.
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.
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.
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.
Abnormal Items
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.
The content of abnormality can be confirmed in the abnormal detection mode explained in
