Yes Peter,
both phones are now working. I've put one in my bedroom and the other in the living room. From what I've understood if you select base 1 on the menu, when you press the round button and scroll the wheel you only see the entries number. However if you select auto select for the base you can also see the message: Open base 1.
No idea about the difference but either way they work well with the updated phonebook.
Thanks again
B
