Press the MESSAGE/Message button to call the

• When a power failure occurs...
All functions of the PBX and Panasonic PTs stop. The
following outside (CO) lines will be connected to the
assigned single line telephones (SLTs):
Outside (CO) line 1: extension jack 01
Outside (CO) line 4: extension jack 09
Outside (CO) line 7: extension jack 17
This allows outside (CO) line conversations between
the specified SLTs and outside destinations.
• When the power is turned back on...
Your PBX restarts with the stored data automatically.
Memory is protected by a factory-provided lithium
battery. There is no memory loss except for the data
associated with Automatic Callback Busy, Redial, and
Call Park.
