Oculus Go: Make sure the headset is nearby and then press and hold both the back button and the Oculus button at the same time until a light starts to blink on the controller. When the blinking stops it is reconnected and you may resume training.

After you replace the battery in your Oculus Go or Pico G2/Pico 4KS/Pico Neo 3 controller, you may need to sync it to the headset again before it starts working.

Pico G2/4KS: Press the Home button. The indicator light will begin blinking. When the light turns off, the controller is synced.
