• 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.
• The KX-TD1232 is illustrated as the main unit, and the KX-TD170 and KX-TD180 are
illustrated as the expansion units.
