Battery Back-Up
This useful piece of kit provides back-up battery power, so if the mains power fails you will still be
able to make telephone calls for up to eight hours.
The Battery-Back-Up has several lights located on it which tell you its status.
These lights may be useful to help you troubleshoot any problems with your connection.
