Troubleshooting
If a power failure should happen...
Your KX-TD816 or KX-TD1232 System enables conversations between specific CO lines
and SLTs (Power Failure Transfer), and supports system data backup.
Power Failure Transfer
All the other conversations except for the above combinations are disconnected during a
power failure.
When the power restored after a power failure, your system automatically restarts its
operation keeping the previous system data as much as possible.

mode.
