I hate to be beaten but I think this one has done it. I was given this phone the other day, plugged it in and thought 'Hey! This is great!'. About half an hour later it was displaying 'No base found' on the handset. Weird. Studied the books, changed the batteries, plugged it directly into the main socket instead of the shared one, tried registering the handset to the base - and all else I could think of in the book. Nothing. I unplugged it and reconnected the old phone. A few hours later, not wishing to give up, I reconnected it and it was fine. For about 20 minutes. As it showed that it was charging the batteries, I took them out and charged them separately overnight. Connected it all up and it was fine. For about 20 minutes! Strangely enough, if I ring from my mobile, it rings.
Does anyone have any ideas or is this one for the bin?
