4. Install the new BCU in the machine.
5. Enter the machine’s serial number into the BCU (SP5-811-004).
• If the machine’s serial number is not entered correctly into the new BCU, SC995-01 (serial
number entry error) appears.
6. Turn the main power switch off and on.
7. Set the DIP switches on the new BCU board to the same settings as the old board.
• Make sure the EEPROM is correctly installed on the BCU. Insert the EEPROM in the EEPROM slot
with the "half-moon" pointing [C] to the downside.
