Loosely sleep related but wasn't sure where else to post.
We have the angelcare monitor which has been fantastic for the last 3 years until yesterday!!
Absolutely nothing has changed regarding the monitor - it's position etc but yesterday it started with a really weird interference/repetitive buzzing (almost purring) noise. On occasion it's also seemed to pick up sounds from another monitor as we've heard talking/lullabies but it's generally just the repeated buzzing noise.
I've changed the channel several times, I've switched off all electrical sockets nearby (though it's never been a problem before), I've switched off and on again, and tonight I've spent a tenner on brand new batteries for it but it's still doing it.
Has anyone experienced this and found a solution?? It's well out of warranty at 3y old so it seems pointless approaching angelcare but I'm gonna give them a call to ask if I'm missing something.
