1. Before your first flight ensure you have completed a full bench test and followed the
instrucitons in this User Manual, including performing an Advanced IMU calibration and
Compass calibration.
2. Remote controller, aircraft battery, and mobile/tablet device are fully charged.
3. Arms are fully extended and locked into place.
4. Propellers are mounted correctly, level and securely locked in place.

Calibrating compass

IMPORTANT: Make sure to calibrate the compass before each flight. The compass is very sensitive
to electromagnetic interference, which can cause abnormal compass data leading to poor flight
performance or even failure. Regular calibration is required for optimum performance.
- DO NOT calibrate your compass where there is a chance of strong magnetic interference, such
as magnetite, parking structures, and steel reinforcements underground.
- DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular
phones.
- DO NOT calibrate beside massive metal objects.
- YOU MUST calibrate your compass in every new flight location - including your FIRST FLIGHT.
Calibration procedure
Choose an open space to carry out the following procedures.
1. Ensure the compass is calibrated. If you did not calibrate the compass when performing your
checklist, or if you have changed your position since the last calibration, tap the 'Aircraft Status'
indicator bar on the DJI GO app and select 'Calibrate" and follow the on screen instructions.
2. Hold and rotate the aircraft horizontally 360 degrees anti-clockwise, and the Aircraft Status
Indicator will display a solid green light.
3. Hold the aircraft vertically with the nose pointing downward, and rotate 360 degrees anti-
clockwise, around the center axis. Recalibrate the compass if the Aircraft Status Indicator shows
solid red.
If the Aircraft Status Indicator blinks red and yellow after the calibration, move your aircraft to a
different location to carry out compass calibration.
Calibrate the compass before each flight.
