IV. Exit program mode
Move the throttle stick to the bottom position within 3 seconds after you hear two long beeps and one short beep (emitting from the motor) can get you exit the programming mode. The motor beeps “Number” beeps to indicate the number of LiPo cells you have plugged in, and then a long beep to indicate the power system is ready to go.
