Question Author
Well, its all done. The engineer was in an out so quickly, I'm surprised he had time to do anything, let alone answer any of my questions.
Anyway, I can probably find out myself. One thing though, as soon as he had programmed the 'thing' he took the phone cable out, and just left it at the back of the set.
I am a bit scared of it at the moment, the cables are like french knitting at the back, can I unplug the plugs to sort them out. Also, do you unplug yours when you go away, or at night etc.
Thanks for any help ypou can give me.
