Failure Transfer
Power Failure Transfer connects a specific standard telephone to a
selected outside line in the event of system power failure, as
follows:
Outside Line 1 – Extension (T, R) Jack 1
Connection of outside line 1 and the respective extension require
no auxiliary connection.
Note
• In the event of a power failure, system memory is protected by a
factory-provided lithium battery. There is no memory loss except the
memories of Camp-on, Saved Number Redial, Last Number Redial,
Call Park and Message Waiting.
• The system changes the current connection to this connection
automatically when the power supply stops.
• If DC power is available from backup batteries if AC power fails, the
system does not change the current connection to the above connection.
