Hello and good day Airheadbit. Thank you for reaching out and for the inquiry. I will be posting a link where in you can find the user manual for the DJI Goggles RE ( https://dl.djicdn.com/downloads/ ... _User_Manual_EN.pdf ). This user manual will also contain the information with regards to the DJI Ocusyn Air System. In addition I will be posting an official DJI turorial video on How to Activate the DJI Ocysync Air Unit . Thank you.
