When the PlayStation VR2 headset is turned on, the Sense controllers will robotically activate as properly. To show off the Sense controllers, press and maintain the PlayStation button on the left controller for about 5 seconds till the sunshine bar flashes orange and the controllers vibrate. You can even flip off the Sense controllers by going to the Settings menu within the PlayStation VR2 headset and choosing ‘Controllers’ > ‘Flip Off Controllers’.
Turning off the Sense controllers when not in use may also help to preserve battery life. The controllers may even robotically flip off if they aren’t used for a sure time frame.
