Troubleshooting

If a power failure occurs...
Your system allows certain extensions to make and receive calls on certain lines (Power
Failure Transfer) and retains system programming.
Power Failure Transfer
A specific extension will be automatically connected to a specific exchange line. This provides
exchange line calls between the following extensions and exchange lines.
Exchange line 1 is connected to extension port 01.
Exchange line 4 is connected to extension port 09.
