HTC VIVE Focus 3 - I can only see the HTC VIVE logo as a white spinning wheel

This means that the headset has not been able to find enough tracking information.

Please position yourself in the room centre point and rotate slowly around yourself 360 degrees until the tracking is found. This way we allow the headset to easily recognize the tracking marks and position itself.

If after 1 minute the tracking has not been found, please reset the headset.
