Don't throw it away yet! I ordered a high capacity battery from e-Bay, not JVC, hooked it up, got the Communicating Error. It's may be just your battery if your issue is like mine, as I put the regular battery back in and it operated just as normal. The new battery had a pigtail that had to be hooked in where the charger normally goes. Time will tell, but in my case, it is the battery. Don't know if it's defective or what the issue is but that's the issue in my case. So anyone reading this thread don't be throwing it away yet. Check the battery first.
