SERVICING NOTE
PRECAUTION ON REPLACING THE BOARDS
The supplied boards are all type C, and therefore if the board is
replaced, use the board of type C only whichever model is ser-
viced.
However, on the type C model, the number of pins of connectors
that connect MAIN board to CD board, and MAIN board to
POWER board has been changed, and accordingly the type C is
not interchangeable with type A and B respectively.
Therefore, if even one of MAIN, CD, and POWER boards is re-
placed, replace all three boards simultaneously.
