Thanks for replying to my question. I'm not very confident with the internet but I'll do my best.
I think the phones are about 10-12 years old but I've misplaced my documentation so they might be older than that. They were working perfectly until I had a power cut and, although the fridge and the cooker and everything else that was on the same circuit is up and running again, my 2 phones (the base is plugged in in the kitchen where the power cut was) are just flashing "base 1" and I don't know how to get them useable again. The phone rings when someone calls me but I can't hear them, there is no familiar tone, and no communication with the person ringing and I can't make a call.
My daughter Ruth, is trying to help me but she is in a flat on the other side of town and studying for exams so it's a bit difficult for her. I would be grateful if you would send any information that you give to me to her email address too (*****@******.***). She has given me her permission to ask you this. Together we might be able to figure it out.
Thank you very much for trying to help me Michael. I'll take your advice (I was already thinking along those lines myself but I would never have known if I'd done the right thing or not).
So your advice was much appreciated. I feel relieved to know what to do now.
With thanks, Essel
