Installation 2-55
2.5 Power Failure Transfer Connection
Notes • In the event of a power failure, system memory is protected by the
factory-provided lithium battery. There is no memory loss except for
the saved values of the Camp-on, Saved Number Redial, Last Number
Redial, Call Park and Message Waiting features.
• The system automatically changes the current connection when the
power supply stops.
• If DC power is available from backup batteries in the event of an AC
power failure, the system does not change the current connection.
