Aurora comes with a removable clip to facilitate the use of the device on different aircraft. The clip is designed to be mechanically sufficiently tight to not come loose accidentally during flight. You can install the clip to the UAV using the double-sided tape included in the packaging, or any other suitable method.
The clip is not symmetric: You must insert Aurora in the right orientation. Start with inserting Aurora on the side with the wider flange first, and then push the side with the narrow flange.
In order to remove, push the narrow flange of the clip away from the device, and lift the device off.
