Battery Back Up Unit beeping

If your Battery Back Up Unit starts to beep, check it hasn't been disconnected from the mains power by accident. If it continues to beep and you also have a red light, contact us so we can send out a replacement.

If it starts to beep during a power cut, you'll still have at least an hour to make calls.
