Troubleshooting
If a power failure should occur...
Your KX-TD500 System enables conversations between specific CO lines and extensions
(Power Failure Transfer), and supports system data backup.
Power Failure Transfer
Specific extensions are automatically connected straight to specific CO lines. This provides
CO line conversations between the pre-assigned extensions and CO lines:
•
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 re-starts
operation, maintaining as much of the previous system data as possible.
