Thanks for replying. I have the original and a new handset and bases.
The whole operation was bought in 2010 and everything worked perfectly.
The main handset and answerphone still work perfectly but the second handset is the problem, it suddenly stopped working about a year ago, then I bought a new secondary handset and base, this did not work either.
The only thing I did do about that time was move the telephone extention across the upstairs room - some 4 feet, with the modem still in place.
The computer works perfectly and the main phone handset work OK the problem is confined to the second handset. I have relocated this handset to the main phone base and this still shows 'out of range' I have changed the batteries over -still the same. I cannot imagine all the handsets (3) to be 'out of range'. I am at a loss as I don't know of a BT shop with a specialist engineer who I could take the whole lot too. I want help please
Thanks for your help, I have tried all you asked to no avail.
With your fee and two more sets of batteries it is getting expensive, so unless you can think of something else I will cut my losses and buy new- not a BT product. I am away for a week so cannot reply, but hope you can think of something
