Click the question, and browser will take you to the web-page with the answer :
To Take a Screen Shot : Simultaneously hit the OCC Button and either trigger
To FULLY power down : Hold the off on side of headset until "power off" menu asks for confirmation. Don't take off headset till after screen goes black, then gets darker as power stops..... sometimes they go dark then darker so close you can't separate, other times it takes a moment between and if you take of headset too soon it won't fully power off.
