3.4 Pairing & Calibration
Before the first flight, or after any impact, it is recommended to perform compass and gyroscope calibration.
- Power On: Turn on the remote controller, then press and hold the power button on the drone for 3 seconds. The drone lights will illuminate and begin to flash rapidly.
- Pairing: The remote controller will emit two "Beep" sounds, and the power indicator light will stay solid, indicating successful frequency pairing.
- Compass Calibration: Follow the on-screen prompts on the remote controller. Hold the drone level and rotate it until the remote controller beeps once. Then, rotate the drone vertically until it beeps again. The front lights will stay solid, and rear lights will blink slowly, indicating successful compass calibration.
- Gyroscope Calibration: Follow the on-screen prompts on the remote controller. A remote controller beep will sound as the lights transition from rapid flashing to a solid front light with slow-blinking rear lights, indicating successful gyroscope calibration.
