Power Failure Restart
Description
When the power returns, the system restarts the stored data automatically. Before restarting, 
the system records the error logs if necessary.
Conditions
In the event of a power failure, system memory is protected by the factory-provided lithium 
battery. There is no memory loss except the memories of Camp-On and Call Park. However 
if the system finds the wrong system data, the indication "Memory data loss" is displayed 
on the digital proprietary telephone with display of Operator 1.
If your area often has power failures, we recommend that you connect backup batteries. See 
the Installation Manual, 2.6.1 Backup Batteries Connection.
