Everything works fine, but the green light on the base unit flashes all the time. According to the manual it should only flash when being rung, during a call, or searching for handsets.
I have tried de-registering all handsets other than 1 and 2, but get a long beep indicating that they don't exist, which is true.
A call to BT got the answer "don't worry about it if it works". Has anyone else got the same symptom? If so, it must just be duff software.
