Function
The machine initializes the parameters, user switches, firmware switches and assurance mode
switch settings registered in the EEPROM, to the initial values. Entering function code 01
initializes almost all of the EEPROM areas, but entering 91 does not initialize some areas, as
listed below.
NOTE: If you replace the main PCB with the one used for any other machine, carry out this
procedure and then customize the EEPROM (function code 74 in Section 9.4.23 ).
