Had trouble getting battery compartment open so e-mailed RCA. Not easy. Actually you will eventually get to Audiovox. Was informed on how to open the battery compartment. Turned out to be very easy. Just hold ear piece in the palm of your hand and put the other hand's palm on the removable piece and push down and turn in direction indicated. Presto! After inserting batteries and charging them for required time plugged the head set into TV. Nothing! The charging light works but the power light does not. I have e-mailed RCA again to see if I did not do something right. The previous ear phones I used in the TV work just fine. I wanted to use those elsewhere. The TV I want to use them with is at a vaction home 100 miles away. I will be returning these if RCA can't give me help.
