Notes on replacing board
On the B, T and Q boards
When any of either the B board 1-682-390-14 or the T
board 1-682-396-12 or the Q board 1-682-395-13 is going
to be replaced, replace these three boards at the same time.
Reason : Because there are changes of EXT SYNC
between the B and the T board, and because
there are changes of 3.3 V power line between
the T and the Q board, the machine will not work
if any of these is left in the former board.
On the D1 and the G board
In the new board, the connectors CN1504 (D1 board) and
CN502 (G board) are changed from 5 pins to 6 pins, the
mating connectors must be inserted by aligning to pin-1.
