If a system password is forgotten, it can be found by loading a backup of the system data into a
PC, and checking the password using the Maintenance Console software. If you do not have a
backup of the system data, you must reset the PBX to its factory defaults and reprogramme it.
Therefore, we strongly recommend maintaining a backup of the system data. For more information
on how to back up the system data, refer to the PC Programming Manual.
However, as system passwords can be extracted from backup copies of the system data file, do
not allow unauthorised access to these files.
