Did this battery swap work for you? I have had mine do this same clicking sound and I assumed it was the battery. I bought a pair from Amazon and replaced but it still does not work. I still have the clicking sound. Really frustrated as I have never got this system working to my satisfaction. I had it working briefly with the hovi tip speakers but found that while great in the house alone, it was not loud enough to hear at a Con which made it all but useless. But now since getting my hands on a proper Aker 1505, I have not been able to get it to work. Just keeps getting this clicking sound even after a battery replacement.
Anyone have any advice for me?
