Panasonic telephone set (Aigburth L19)

Not new KX-TG6421ES. Please read all parts of this post and respond together with your mobile number. This item will only work if your existing system is hard wired into your house. If you have full fiber into your house you will need an additional box to connect to your fiber supply. May need some new batteries soon. I do not have any instructions but can be found on line. Collection only from Aigburth later at an arranged time.
