This is probably a very stupid question in this forum of experts.
However - we have inherited a couple of old M3820's from another company.
When I try to plug them into an ordinary phone plug, they do flash on, but they do not seem to work. I do not get any clear tone when I lift the handset. None of the buttons seem to work.
What is wrong?
