If you’re ever feeling lost in your Astro C40 digital camera, or if you just want to reset it to its factory settings, there are a few things you can do. First, make sure that the camera is off and unplugged. Second, remove all of the battery cells from the camera. Third, insert a new battery into the camera and plug it in. Finally, turn on the camera and take a picture or two to test it out. If everything goes according to plan, your Astro C40 should now be set back to its factory defaults.
