We sold a demo TSU9600/RFX9600 to someone and now he is saying that the remote works fine while on the dock, but as soon as he picks it up it goes black. He also says that while it is in the dock there is supposed to be a red LED that lights up while charging, but it is not lit (even though the remote is getting power and functioning).

I had this unit sitting on my desk for few weeks and I was leaving it on the dock for a while, pulling it off and leaving it un-charged for a few days, putting it back on the dock for a few days specifically to test the battery before we sold it. It had been unused for a while before this.

Has anyone experienced anything like this? I need to point this guy in the right direction.
