A:Answer You may have the battery in upside down. I've done that. When you put in the battery, just tap the Fit Bit to make sure you see lights, if not turn it around, if you still don't, it could be the battery. I did have to take one back because the battery didn't fit the band tight enough for it to be read. As far as seeing your report, you need to download the FitBit app on your phone. It will even let you know when your battery is low and needs recharging. If you're a visual person just look up Fit Bit on You Tube for videos to watch. It really is pretty simple to set up.
