I have been following the set up and help facilities on the website to reconnect an internal chime that no longer chimes. I suspect I know how this happened - see below. But in order to resolve this I needed to follow the step by step guide. I have now reached the point where I get a message that tells me - how/why is inexplicable - that my device is registered to another and cannot be set up or the registration request actioned. Where do I go from here? The likely reason for the need for a reset/reconnect I have now realised - 2 weeks later after only just realising my doorbell has not rung - is that we have just moved to fibre broadband with a new route and thus password.
