1. Replacement of MAIN board
This board is provided with a memory device (EEPROM) that stores the adjusting data singular to the machine
and also the operation setup data. This memory device can be out of order due to a problem in the board.
However, since precious data are stored there, it is recommended to transfer this memory device to a new board
after replacement.
According to the diagram shown below, replace the MAIN board carefully, not to damage the EEPROM terminals.
