Note on Main Board Replacement
Take the following setting when the main board is replaced.

is printed on the rating label on the cabinet, the other one is displayed on the "Information" on the on-screen menu.
The serial no. displayed on the on-screen menu is stored in the memory IC on the main board. When replacing
the main board or memory IC, you need to write the serial no. referring to the serial no. printed on the rating label
with the serial no. setting tool. For further details, refer to the operation manual of the serial no. setting tool [SST
