Hi there, I've today received my used sunset, bought from eBay. Powering up using the same supply that my iridium uses successfully, makes the B light flash and 3 audible clicking noises. I have tried factory reset and alternative power supplies and still getting same issue.
Is this normal behaviour, or do you think it's a fault? Obviously I can return if not working correctly, but would rather confirm as it may be expected. Unable to find info in the manual either.
