JHE20B Finder 100dB Super Loud FPV Racing Drone Buzzer Alarm

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.

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).
