PROBLEM: The gimbal starts up, but the camera is not level.

EXPLANATION: The motion sensor that is on top of the camera mount (known as the inertial measurement unit, or IMU) is precisely calibrated at 21 degrees Celsius at our production facility prior to shipping. However, over time, at different temperatures, or after hard impacts, the sensor can drift away from proper calibration, causing the gimbal to think that "tilted to the left" (as an example) is the actual horizon.

SOLUTION: 

1. Unplug the cables coming from the motors going to the gimbal control board (they are on the left side of the gimbal control board). Take careful note of their orientation and position.

2. Power up the Phantom.

3. Rigidly fix the camera in a perfectly horizontal position (do not just use your hands - make sure it is kept perfectly motionless).

4. Press the small black button on the back of the gimbal once quickly (do not hold it down... this will reset the board completely).

5. Wait approximately 5 seconds for the gimbal to re-calibrate itself. You'll see the green light on the gimbal control board flash for a few seconds, then once it is finished, the green light will be solid again.

6. Now, turn the Phantom off, plug in the motor cables into the gimbal control board, then turn the Phantom power back on.

 

PROBLEM: Manual pitch control is not working through the smartphone app.

EXPLANATION: The small cable coming from the underside of the Phantom 2 Vision, which normally connects to the stock servo, carries a pitch control signal along one of its pins. Our pitch control cable (black on one end, white on the other) takes that signal and passes it into the gimbal. Before shipping, each gimbal is physically connected to a Phantom 2 Vision, powered up, and tested to ensure that the tilt function is working properly (among other tests) through the smartphone app. The problem usually has to do with the pitch control cable not passing the signal properly because one of the connection points isn't proper.

SOLUTION: 

1. Verify that the black end of our pitch control cable is connected as follows:

2. Power up the Phantom.

3. Rigidly fix the camera in a perfectly horizontal position (do not just use your hands - make sure it is kept perfectly motionless).

4. Press the small black button on the back of the gimbal once quickly (do not hold it down... this will reset the board completely).

5. Wait approximately 5 seconds for the gimbal to re-calibrate itself. You'll see the green light on the gimbal control board flash for a few seconds, then once it is finished, the green light will be solid again.

6. Now, turn the Phantom off, plug in the motor cables into the gimbal control board, then turn the Phantom power back on.
