First, you should unlock the battery compartment of your camera. After that, you need to open the battery door backward and lift the door towards the compartment. With this, you need to show the battery and close the battery door. Then, you must bring your security system within three feet to the base station range. And for the Arlo setup guide, you have to sync the camera to the base station. If you use the Arlo base station, at that time you will have to sync the button on the side station or behind the base station.
