When to Recalibrate:
- After any firmware/software update
- After a crash (minor or major)
- Flying in different location to last flight (far away)
- When drifting occurs in flight, i.e. Phantom does not fly in straight lines.
- When hovering, Phantom wants to fly in a circular pattern (Toilet bowl effect-TBE)
- When compass data is abnormal, the rear LED flight indicator will blink Red and Yellow (See “Led Status” section). - Something magnetic (screw driver with magnetic tip, speaker, magnet ...) got close to your compass/aircraft.
- Mechanical structure of the Phantom has changed, i.e. changed mounting position of the compass.
- If compass calibration is needed before flight, a prompt will appear on the DJI Vision app’s camera page.
Need to Know: You do not have to calibrate your compass before every flight (meaning: don’t become compass calibration crazy); this is not necessary and may actually increase your chance of having a problem. You don't want to risk introducing any issues that weren't there before by recalibrating too often. DJI recommend recalibrating only when moving far away from last flight point.
- Do the Calibration in a WIDE open space. Not in your house, your garage, near your car...
- DO NOT carry ferro-magnetic materials with you during calibration such as keys or cellular phones.
- DO NOT calibrate in areas that could have high magnetic EMI interference such as areas that are close
to power lines, cell phone towers, parking structures, reinforced concrete or steel reinforcements underground. - DO NOT calibrate beside massive metal objects (cars, buildings, fences, buried pipes & cables, etc).
Note: Compass Calibration can now also be initiated from DJI Vision - Settings page instead of using the S1 Switch.
