GPS & Compass Calibration

If the Compass Module is not used, you can skip this step.

The GPS module has a built-in magnetic field sensor for measuring the geomagnetic field, which is not the same in

different areas. The GPS module will not work unless the Compass Module has been connected. Make sure the

Compass Module connections are correct.

Please always keep the compass module away from the magnet. If this situation occurs please change the compass

module before flying. Otherwise it may damage the compass module and lead the aircraft to work abnormally or even

be out of control.

Calibrate the compass before the first flight or when flying in a different area.

Make sure to keep away from

ferromagnetic substance and other electronic equipment when calibrating or flying. If you keep having calibration

failure, it might suggest that there is magnetic interference or other ferromagnetic substance, please avoid flying in this

area.

If you have calibration failure or the LED blinks red and yellow lights alternately (

), please connect to

the Assistant Software, select the “Tools” tab and follow the tips of the “IMU Calibration” to do operation.

1. Quickly switch the control mode switch from

ATTI. Mode

GPS ATTI.

Mode

and back to

ATTI. Mode

for 6 to 10 times, The LED indicator will turn

to constantly yellow.

2. Rotate your aircraft around the horizontal axis (about 360

) until the LED

changes to constant green, and then go to the next step.

3. Hold your aircraft vertically and rotate it (its nose is downward) around the

vertical axis (about 360

) until the LED turns off, meaning the calibration is

finished.

4. If the calibration was successful, calibration mode will exit automatically. If the

calibration has failed, the LED keeps flashing quickly Red. Switch the control
mode switch one time to cancel the calibration, and then re-start from step 1.
