1.1.101 Power Failure Restart
Description
When the electricity is turned back on, the PBX restarts and automatically loads stored data.

• In the event of a power failure, PBX memory is protected by a factory-installed lithium battery. There is
no memory loss except the memories of Automatic Callback Busy (

1.1.102 Power Failure Transfer
Description
If the power supply to the PBX fails, specific single line telephones (SLTs) are automatically connected to
specific outside (CO) lines (Power Failure Connections). The PBX will switch from the current connections
to Power Failure Connections, and all existing conversations will be disconnected.
Only outside (CO) line calls handled by Power Failure Connections can be made during a power failure.
Conditions
• During a power failure, each of the following outside (CO) lines will be connected to an assigned
extension.
Outside (CO) line 1: extension jack 01
Outside (CO) line 4: extension jack 09
Outside (CO) line 7: extension jack 17
• Only outside (CO) line calls are possible during a power failure. All other features will not function.
• We recommend connecting an SLT in parallel at extension jacks 01, 09, and 17, so that the SLT can be
used during a power failure.
