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 straight to specific outside lines. This provides
outside line conversations between the pre-assigned extensions and outside lines:
<KX-TD816>
Outside line 01 is connected to extension jack number 01.
Outside line 02 is connected to extension jack number 02.
Outside line 05 is connected to extension jack number 09.
Outside line 06 is connected to extension jack number 10.
<KX-TD1232>
Outside line 01 is connected to extension jack number 01.
Outside line 02 is connected to extension jack number 02.
Outside line 03 is connected to extension jack number 09.
Outside line 04 is connected to extension jack number 10.
Outside line 09 is connected to extension jack number 17.
Outside line 10 is connected to extension jack number 18.
• All other conversations are disconnected during a power failure.
• Digital proprietary telephones (DPTs) cannot be used during a power failure. SLTs can
work in the event of a power failure.
• When power is restored after a power failure, your system automatically restarts
operation, maintaining as much of the previous system data as possible.
