Restore Factory Settings at the Touch of a Button
If the factory settings on the PBX are restored, all of the settings are deleted or reset to the original settings before the device was first configured.
* Warning: Touching voltage-carrying conductors or phone connections can cause life-threatening electric shocks.
For some installation and maintenance work, it is necessary to open the PBX while it is in operation (qualified electrician only). Make sure that the PBX is never left unattended while working with an open casing. Close the casing after completing this work.
Only a qualified electrician may perform installation work within an open casing or service work using the buttons inside the casing. If necessary, commission an authorised dealer to perform this work.
* Warning: Power surges, which can occur during electrical storms, can cause life-threatening electric shocks and damage or destroy the PBX.
Do not open the PBX during an electrical storm.
