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 performed with the MAIN board removed, the POWER switch (S303)
must be fixed to ON state.
– MAIN BOARD (Conductor Side) –
CHANGE THE SPECIFICATION (US Model Only)
For the mounted MAIN board (A-3021-325-A), the TAP101 and
201 patterns are opened.
This specification is for the Canadian, AEP, E, and Chinese models.
Accordingly for the US model, short the TAP101 and 201 with a
solder to change the specification.
