COMPASS CALIBRATION PROCEDURES
Please follow the calibrating procedures before the first flight.
1.) Hold the Throttle Stick fully down, bob the GPS switch quickly until the transmitter displays "
Calib compass 1"
2.) Rotate the X4 horizontally in clock-wise until the LCD screen displays " Calib compass 2"
3.) Put the X4 nose down and rotate it vertically in counter clock-wise until the " Calib compass
2" on screen disappears.
4.) Calibration done.
Do not calibrate the compass in a strong magnetic field
Do not carry ferromagnetic materials with you while calibrating the compass,
such as keys, cell phones.
Compass calibration is required before the first time flight otherwise the system may not work
properly. The compass is very sensitive to electromagnetic interference which can cause
abnormal compass data and lead to poor flight performance or even flight failure. Regular
calibration enables the compass in optimum performance.
