Dear all - first time poster!
I have a BT 3960 (additional hand set to my base unit) which I want to use upstairs - it has a terrible reception there though. I have read that a repeater or extender could help boost my reception but am confused as to the compatability. Could anyone advise the correct repeater product that I need to buy . Many thanks
Welcome to this user forum.
Ring the product helpdesk if you want to check for compatibility.
It does say only.
Just to add, you should not really have any issues with those phones, within a normal house, unless you have something causing interference.
