Panasonic Quad Pack Digital Phones with answering machine (Arnside LA5)

This is a pack of four digital cordless handsets with 1x base unit and 3 x chargers.
Has an answering system of up to
40 minutes.
This will only work with an ANALOGUE set up (i.e. an old fashioned landline) not the new copper line.
Original handbook and quick set up leaflet is in the box.
All working well last time it was used.
