Charge it from the wall (can use the supplied USB and an iphone charger head) - during charging the light on the front it solid red and turns off when complete
Turn the camera on using the button on the side. The green light under the lens will flash for a little and so will the wifi logo on the bottom of the camera. Once this has finished flashing, go in to the settings menu on your iphone and select wi-fi, let it search and FC40 followed by numbers should come up. May take a couple of searches for it to appear. When it does tap on it to connect to it.
Once that's connected, open the FC40 app and it should show you the same FC40 xxxxxxx in the white box. Tap that and it should work.
