This question is a bit ambiguous. It could be asking about two things:
1. Turning on your VR Headset:
To turn on your VR headset, you'll typically find a power button somewhere on the device. It might be on the side, the front, or the back.
- Look for a button that looks like a power symbol (a circle with a line through it).
- Press and hold the button for a few seconds.
- The headset should power on and display a startup screen.
2. Turning on VR Mode on your Nintendo Switch Console:
To play VR games on your Nintendo Switch, you'll need to use the Nintendo Labo VR Kit. To enable VR mode, follow these steps:
- Connect the Labo VR goggles to your Switch.
- Open the Nintendo Switch home menu.
- Navigate to the "System Settings" icon.
- Scroll down and select "VR Mode."
- Turn on the VR mode switch.
Once you've enabled VR mode, you can launch any compatible VR game from the Nintendo Switch home menu.
