The buzzer has two modes of operation:
- It is compatible with the functions of the traditional active buzzer and synchronized with the flight control.
- When flight control is normally connected, if the main flight battery is turned off, it can still emit automatically 100 dB of sound to drop after 30 seconds of power failure and the LED will emit a white light.
To deactivate 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 flight controller buzzer interface and it will work. When the flight control wiring is correct, the multi-rotor aircraft is on and the flight control power supply will be automatically loaded for the JHE20B Finder (the red LED will light up to indicate charging is in progress, the red light is off to indicate the saturation of the charge; flashing red light indicates flight control) Electricity, to insert 30 seconds of waiting).
