Query: Mostly DOA

This product did not work. The audio only lasts 5-10 seconds. If I turn it off and then on or hit the resync button, I get 5-10 more seconds of audio. It doesn't matter how close I am to the base. I had recentely sent back my RS140's to be fixed (they worked great for 2 years). I won't be purchasing any refurbished units again.
