If a power failure should occur...
Your system enables conversations between specific outside lines and extensions (Power
Failure Transfer), and supports system data backup.
Power Failure Transfer
Specific extensions are automatically connected directly to specific outside lines. This
provides outside line conversations between the following extensions and outside lines:
Outside line 1 is connected to extension jack number 1.
• All other conversations are disconnected during a power failure.
• Digital proprietary telephones (DPT) cannot be used during a power failure. Standard
telephones can work in the event of a power failure. Connect them to the above jacks.
• When power is restored after a power failure, your system automatically restarts
operation, maintaining as much of the previous system data as possible.
