Set of cordless phones (Wilstone HP23)

Set of four cordless phones - PanasonicKX-TG8521E
Comprises:
- One master base station
- Three satellite base stations
- Four handsets
- Four power adapters
- One phone-line cable
Handsets each require 2xAAA batteries which are NOT included.
I have every reason to believe that this all works, but I do not have a telephone line with which to test it to be certain.
