Auxiliary Connection for Power Failure Transfer
Power failure transfer connects a specific single line telephone (SLT) to selected exchange
lines in the event of system power failure, as follows.
Exchange line 1 – extension (T, R) port 01
Exchange line 4 – extension (T, R) port 09
Connection of exchange lines 1 and 4, and the respective extensions require no auxiliary
connection.
• In the event of a power failure, system memory is protected by a factory-provided lithium
battery. There is no memory loss except the Camp-on, Saved Number Redial, Last Number
Redial, Call Park and Message Waiting memories.
• The system automatically changes the current connection to the above connection when the
power supply stops.
• Proprietary telephones cannot be used during a power failure. Therefore, we recommend
connecting SLTs in parallel with proprietary telephones connected to extension ports
01 and 09.
