3.3 MEMORY BACKUP
A non-rechargeable lithium battery provides long-term backup for the SRAM on the
FCU, so that system parameters and programmed settings are maintained even
when the base copier is unplugged or its main switch is turned off.
A rechargeable lithium battery backs up the SAF memory (SDRAM) on the FCU for
about 12 hours in the event that power goes off.
