Features of the JHEMCU JHE20B Finder
 The buzzer has two operating modes:
1. It is compatible with the functions of the traditional active buzzer and synchronized with the flight controller.
 2. When the flight controller is normally connected and the main battery is turned off in flight, after 30 seconds of power failure, it can still automatically emit a dripping sound of 110dB and the LED emits white light.
  
 To turn off the buzzer:
Press and hold the release button for more than 2 seconds. The JHE42B Finder will mute the sound.
  
 Info:
The JHE42B Finder is compatible with all BF, CF and INAV flight controllers. Just connect it to the buzzer interface of the flight controller and it will work. If the flight controller wiring is correct, the multirotor aircraft will be powered on and the flight controller power will automatically charge the JHE42B Finder (the red LED is on to indicate charging, a red LED off means charging is complete; a red LED flashing means the flight controller is off; wait 30 seconds).
