When restoring data files, it is important to identify each file and understand what type of data will be restored
(overwritten), as this process is irreversible. A safe way to restore data files is to make a fresh backup of all
system data before. The data files that their name starts with ‘EDF’ will restore all events, panic buttons, alarm
inputs programming. The data files that their name start with ‘SDP’ will restore all VS4820 configuration and
setup parameters. The files that their name start with ‘SDB’ will restore the schedule event programming.
