What to do if my Panasonic KX-TDA15 PBX telephone does not respond when buttons are pressed?

There are a couple of potential causes: * The telephone is locked, so unlock your telephone. * Your telephone is connected to an eXtra Device Port. If this is the case, system programming is required, so consult your dealer.
