At first Glance, everything looks excellent!! Haven't used it in a live game scenario till Oct 1st. I do have several questions? What is the USB option for? What exactly is the antenna for? Can It connect to a Much larger Reader display through the usb? Can it connect to actual Bing software? Can my reader board flash the number called, continuously or just for a short period and then return to stagnate? The reader board shuts down after a period not in use, how long is that period? you have to wiggle and press the ball down on the board sometimes to get it to read , is this normal?
