Just got my Halo (not the LCD version) just the single light and single power button. As soon as I install the batteries it goes into what I'm guessing to be a self test, all fine and good, green light flashes, hopper works as it should. Push the button to turn it off light turns red and stays on, light will not go out and it won't turn green or start working again unless I remove and reinstall the batteries. The directions it came with are for the LCD hopper, what am I doing wrong???
