Model: JHE20B
Size: 22*12*9.5MM
Weight: 2.7 grams

The buzzer has two modes of operation:

1. It is compatible with the functions of the traditional active buzzer and synchronized with the flight control.
2. When the flight control is normally connected, if the main battery in the flight is powered off, it can still automatically emit 100 dB of drip sound after 30 seconds of power failure, and the LED will emit white light.

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 be automatically charged for the JHE20B Finder (the red LED will light to indicate charging is in progress, the red light is off to indicate charging saturation; the red light flashing indicates flight control) Electricity, enter 30 seconds waiting time).

Q:
I installed this on a MAMBA F405DJI stack but as you plug in the quadcopter battery it has an immediate long beep that never stops and the LED is also white. Are these only compatible with specific FCs?

A:

That's probably because you connected the signal wire to the wrong location (ground pad?). To use it on a mamba stack, connect red to buz+, signal to buz- and blak to a ground pad on the FC. Hope this helps.
