Quick Reference

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.
