Our chordless handset started showing unregistered, after a pair of little fingers was playing. We no longer have the instruction manual, so are not sure what unregistered means - either way - it's impossible to recieve incoming or make outgoing calls

Any advice?

Unregistered would mean not set to base unit. Switch it all off, take the batteries out, leave a couple of minutes, restart every thing, putting batteries back in. Try a search on internet, should be able to get instructions.
