machine.
2. Print out the SMC data (SP5-990-001).
3. Turn the main power switch off.
4. Install an SD card into SD card slot 2. Then turn the main power on.
5. Copy the EEPROM data to an SD card (SP5-824-001) onto the SD card.
6. Turn off the main power switch. Then unplug the power cord.
7. Replace the EEPROM on the BICU and reassemble the machine.
8. Plug in the power cord. Then turn the main power switch on.
When you do this, SC995 will be displayed. However, DO NOT turn off the main power switch.
Continue with this procedure.
9. Copy the data from the SD card to the EEPROM (SP5-825-001).
10. Enter the BICU serial number.
11. Turn the main power switch off. Then remove the SD card from SD card slot 2.
12. Turn the main power switch on.
