How to Calibrate the Compass on the DJI Phantom 4 RTK

You may notice your controller displays a warning about the compass. Luckily, the calibration process is quick and easy to complete in the field.

Before you start

• Do not calibrate your compass where there is strong magnetic interference.
  For example, avoid electronic devices, magnetite, parking structures, and underground steel reinforcement.
• Do not carry your phone/radio while performing the calibration.

Instructions

Move into an open area, then follow the procedures below:

Quick Method

1. Turn on the drone and controller.
2. Press the fly button so that you can see the camera view.
3. Locate the flight mode switch (P-A-F) on the left-hand side of the controller.
4. Rapidly move the mode switch between P-F several times
5. The compass calibration prompt should appear on the screen.

Normal Method

1. Turn on the drone and controller.
2. Press the fly button so that you can see the camera view.
3. Tap the three white dots in the top right-hand corner to bring up the aircraft settings page.
4. Scroll down and tap Advanced Settings.
5. Tap on IMU and Compass Calibration.
6. Tap Calibrate Compass.

Follow the instructions to complete the calibration.

1. Once the rear status lights have turned solid yellow, hold the craft horizontally and rotate it 360 degrees counter-clockwise.
2. Once the rear status lights have turned solid green, hold the craft vertically and rotate 360 degrees around the center axis counter-clockwise.
3. The status lights will flash green if the calibration has been completed successfully.

Troubleshooting

If the status lights are flashing red, the calibration has failed. Check that nothing electronic or metallic is nearby and start the process again.

If it is still failing, move to a different location.

Sometimes, a source of interference on site will influence the compass during flight. It's best to avoid these areas when possible by adjusting your flight plans or flying higher over the source of interference. To pause the mission, change the Mode switch from P to F or vice versa.
