BATTERY CHANGE
SENTRON PAC4200 writes data in a battery-backed volatile memory. The data must be
backed up prior to removing the battery.
F1
in the "CHANGE BATTERY" dialog box starts the data backup. The device copies
the data from the volatile memory to the internal non-volatile memory. The data does not
leave the device.
