Hi Jon, that is so very kind of you. But guess what, I just went to have a play around with it again and there was a message on the screen asking for a name. Somehow or another with out doing anything it has re-registered it self over night/this morning plus I have my contacts back and everything, even though I'd reset the phone and the base yesterday.
I have no idea what exactly went on but my phone is back to normal and fully tested working. All I did was rename the phone a minute ago.
Strange one but once again, Thanks alot Jon for the kind offer.
Oh, does anyone have a link to the old instruction manual for this phone. It must be the older type (mark 1)? where I need to hit dot 7 to bring up the menu.
