10.1.3 Setting of CD mechanism self diagnosis
mode
TOP PREVIOUS NEXT
F15 : CD REST SW abnormal.
At initial setting of CD traverse position, if REST SW ON is not detected even though the fail safe
timer time is over (10 sec), this is memorized as an error and the error number can be cleared only at
the start up of micro-p after reset.
H15 : CD OPEN SW abnormal.
During normal operation, if CD OPEN SW ON is not detected within 4 sec, then H15 shall be
memorized in memory. The error code can be cleared only at the start up of micro-p after reset.
H01 : Deck operation abnormal (reel motor, solenoid and mode SW)
During normal operation, if mechanism error process is executed once by mode switch against the
same deck operation, it is judged as mechanism abnormality and this is memorized as an error.
Conditions for judging mechanism error :
1. Mode switch ON is not detected 800 ms after plunger activation for PLAY/REC process.
2. Mode switch ON in not detected 800 ms after plunger activation for FF/REW process. Or,
Mode switch OFF in not detected 800 ms after plunger activation after detecting Mode SW
ON. Or, Mode switch ON is not detected 800 ms after detecting Modeswitch OFF.
3. If Mode switch comes ON at STOP/PAUSE state (normal condition), this is judge as Error :-
A. Main purpose for this Self Diagnosis is to diagnose a partial short of a deck.
B. Mechanical error process caused by EJECT operation shall not be counted.
C. This error number can be cleared only at the start up of micro-p reset.
F26 : Communication between CD servo LSI and micro-p abnormal
At the time of switching to CD function, SENSE = H shall be detected using DTMS system setting
command. If the error is memorized when SENSE = L is not detected within fail safe timer time (20
msec), [F26] shall be displayed simultaneously.This display shall be retained if the power is ON and
at CD function. If this error occurs, CD operation afterward shall not be executed as in the case of
[NO DISC].
This error number can be cleared only at the start up of micro-p reset.
