Will my existing phone system accessories still work when land line is removed?

@WSH thanks for suffering my poor explanation! My kit consists of three (3) handsets of which the master phone labelled KX-TGC210E connects to the BT 'master socket SC'. The two (2) subsidiaries are labelled PNLC1042 & sit on low power recharging cradles. They're wirelessly connected via DECT to the master phone I now realise. Sorry about my ignorance of the basic facts behind my installation.

No problem.  I just thought I'd spotted something the others had missed.  The internet implied that model was single handset only.  Obviously not true.
