If a power failure occurs...
Your system enables a conversation between a specific outside (CO) line and extension
(Power Failure Transfer) and supports system data backup.

provides outside (CO) line calls between the following extension and outside (CO) line.
Outside (CO) line 1 is connected to extension jack number 01.
Outside (CO) line 4 is connected to extension jack number 09.
• All other conversations will be disconnected during a power failure.
