NOTICE:
The following procedure has to be completed within 30 seconds after entering compass calibration mode.
• Power the transmitter and 350 QX3 on and face the quad pointing North.
• Cycle the top left transmitter switch completely 4 times as shown at the right.
• The 350 QX3 indicates it has entered compass calibration mode by fl ashing the LED orange.
• Complete all 4 rotations of the 350 QX3 as shown in the illustration below within 30 seconds,
rotating the quad counterclockwise 45° between each rotation.
• Hold the quad level, facing North and check the LED.
Green = Ready
Red = Repeat Compass Calibration
• Power on the transmitter and 350 QX3 and place the quad on a fl at, level surface.
• While holding the bind switch on the transmitter, cycle the top left switch 4 times as shown at the right.
• The 350 QX3 will emit a series of slow tones followed by a series of rapid tones, indicating the calibration has started.
• Do not move the 350 QX3 while it performs the accelerometer calibration procedure.
• When the procedure has completed, the 350 QX3 will emit a “happy” tone and the LED will display green indicating
the calibration was successful. If it emits a “sad” tone and the LED displays solid red, repeat the calibration procedure.
