2 Backing Up Data
2.1 Outline
Using the Service Support Tool, you can back up the data of the SRAM mounted to the
main controller PCB.
The SRAM contains the following items of data:
• Service mode settings
• User mode settings
• Various MACHINE DATA
Once you have backed up the data, you may write it to the main controller PCB after re-
placing the PCB; or, you can simplify the work involved in entering service mode or user
mode settings.
It is recommended to back up the data whenever possible using the Service Support Tool
when you have updated the service mode settings or the user mode settings.
