Q If I reset the PBX directly after modifying settings, the modified settings are not
updated in the PBX.
A • When you click Apply, the settings are updated in the PBX, but are not yet saved to the
SD memory card. If system data is not saved to the SD memory card, the PBX will restore
the data that was last saved to the card in the event that the PBX is reset, or power is
turned off and back on again.
Therefore, before resetting the PBX, click the SD memory backup icon to save the
system data to the SD memory card. Alternatively, exit the Maintenance Console. This
automatically saves system data to the SD memory card.
Note
Do not remove the SD memory card while power is supplied to the PBX. Doing so may
cause the PBX to fail to start when you try to restart the system.
Q After reinitializing the PBX, I restored system data from a previous backup.
However, some of the settings have not been restored to their previous values.
