Hi I have a BT synergy twin set and all was well,I changed the batteries rechargable what it said in the manual now the extra hand set will not display anything only a battery icon which is only half way there is no other display showing like there is on my base set. It was working fine then all display vanished and the thing went dead. Hope you can help me as I dont want to buy another one as I was quite happy with the one I got

Hi, The handsets supplied with your system would have come pre-registered but if you adding an additional one you will need to refer to the registering additional handsets section of the user guide (page 81).
The best way is to get a copy of the manual is online from BT.
The following link should do the trick.
