What was hardest to figure out was that when I plugged the USB cable into my computer, the camera no longer worked. I finally realized that plugging it into a computer puts it into USB drive mode where the SD card shows up as a drive in Windows so you can watch or copy your videos. When in that mode, the camera is shut off. However, plugging it into a USB wall charger, powers the unit and lets you use the camera at the same time.
