How to turn off the buzzer:      Press and hold the release button for more than 2 seconds, the JHE20B Finder turns off the sound. The JHE20B Finder is compatible with all BF and CF flight controls. Just connect to the buzzer interface of the flight controller and it will work. When the flight control wiring is correct, the multi-rotor aircraft is powered on, and the flight control power supply will automatically charge the JHE20B Finder (the red LED will light to indicate that charging is in progress, Red LED off means charging is saturated; red light flashing means flight controller is powered off, wait 30 seconds waiting time).
