SERVICING  NOTES
THE OPERATION CHECK AND THE VOLTAGE CHECK
WHEN THE MAIN BOARD REMOVED
This set detects which button of 
[REC]
[PLAY]
[FF]
, or 
[REW]
was pressed using the POWER switch (S303).
However, this button operation cannot be detected if the MAIN
board is removed because the POWER switch (S303) is mounted
on the MAIN board.
Therefore, if the operation check and the voltage check are per-
formed with the MAIN board removed, the POWER switch (S303)
must be fixed to ON state.
