NVRAM on the controller board

SC195 (Machine serial number error) will be displayed if you forget to attach the NVRAM.

If you mounted the NVRAM in the wrong direction, it will cause a short circuit in the
controller board and the NVRAM, and each component will need to be replaced.

Installing a new NVRAM initializes SPs and issues an SC. Reset the SC with the
procedure below.
1. Make sure that you have the SMC report (Factory SP Settings). This report comes with
the machine. (page 2-8)
If you do not have the SMC report, enter the factory settings while referring to the "Factory SP
Settings" (page 4-10).
2. Output the SMC log using one of the following methods:
To print SMC log data, execute SP5-990-001.
To save SMC log data to an SD card, execute SP5-992-001 (SMC List Card Save Function).
3. Turn OFF the main power.
4. Insert a blank SD card in the SD Card Slot 2, and then turn ON the main power.
5. Use SP5-824-001 to upload the NVRAM data from the controller board.
6. Make sure the customer has a backup of their address book data. If not, obtain the
backup by referring to SP5-846-051.

The address data stored in the machine will be discarded later during this procedure.
So be sure to obtain a backup of the customer’s address book data.

Note that the counters for the user will be reset when doing the backup/restore of the
address book data.

If the customer have a backup of the address book data, use their own backup data
for restoring. This is because there is a risk that the data cannot be backed up
properly depending on the NVRAM's condition.
