Return the item under warranty for a replacement.

The Kinect sensor has a motorized mount so the camera can adjust itself up and down to follow movements in the room. If you are getting that message something is either physically preventing it from moving or you have a manufacturing defect (any Kinect should still be under warranty and you should be able to simply exchange it for a working one)

I have a Kinect as well and can tell you that message isn't normal in its use so definately clear the area around the sensor or simply just return it for exchange as stated.

Hi Chris

Kindly specify if you have a "slim" version of the Xbox 360 or the older one?

The error code you have specified here seems to triggering due to a hardware issue of your Kinect device.

If you have a older version of Xbox 360 which requires you to use a separate power supply for Xbox 360 try these steps

1. Turn off the console.
2. Make sure the power cord is plugged into a working electrical outlet.
3. Make sure the USB connector is plugged into the back of the console.
4. The light located near the middle of the split cable should be green.

Post that re-calibrate your Kinect tuner and check if it's working else you may have to get your Kinect device replaced from Microsoft

Aim a flashlight at the kinect sensor. I had the same thing happen to me a few times, all of a sudden. Even though it would be working earlier that day, it started saying not level. I think the sensor starts looking all around the room, and aiming a light at it forces it to become center aware again. Idk, but I used the flashlight app on my iPhone, if that helps.

Error: The Kinect Sensor is not level (C0051209)
Place the sensor on a level surface and try again. Here's what to do to fix this problem:
- Turn off your Xbox 360 console. - Make sure the Kinect sensor is positioned on a flat, level surface. - Turn your console on to see if the problem still occurs.
This error can also occur if your sensor is very hot or cold. In this case, wait for the sensor to reach room temperature (approximately 70 °F or 21 °C), and then try using the sensor again.
If these steps do not solve the problem, the sensor will need to be repaired. To start the online repair process, go to myservice.xbox.com.
