Power failure note (Only for use with single line telephones)
If power to the unit fails, the system will not work as usual. The unit does not have an internal
backup power source.
However, it is programmed for backup protection. In the event of a power failure, extensions
00 and 01 become directly connected to outside lines 1 and 4 (for IPS 308 model, lines 1 and
3). A single line telephone must be connected at extensions 00 and 01. You will then be able to
receive and make calls as usual. All other extensions and outside lines will be inoperable until
power returns.
