The machine stores the engine data in the NVRAM on the BICU, and stores the other data in the
NVRAM on the optional controller. To distinguish between the engine data and the other data, see
SP5-801-003 through 015. This service program (SP5-801) handles the controller data. The data in the
BICU NVRAM (engine data) is cleared by SP5-801-002 while the data in the controller NVRAM
(controller data) is cleared by the other programs in SP5-801 (for exceptions, see "Exceptions" as
described below).

Exceptions

SP5-801-002 clears most of the settings and counters stored in the NVRAM on the BICU (the values
return to their default values). However, the following settings are not cleared:
• SP5-811-003 (MachineSerial [ID2 Code Display])
• SP5-812-001 (Service TEL No. Setting [Service])
• SP5-812-002 (Service TEL No. Setting [Facsimile])
• SP5-907 (Plug & Play Maker/Model Name)
• SP7 (Data Log)
• SP8 (Data Log2)
Use SP5-801-002 after you have replaced the BICU NVRAM or when the BICU NVRAM data is
corrupted. When the program ends normally, the message "Completed" is displayed. When you have
replaced the controller NVRAM or when the controller NVRAM data is corrupted, use SP5-801-001.
The message is the same as the basic machine.
