Never loose your Quad again with this super loud buzzer, LED light and built in battery!
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 110 dB of drip sound after 30 seconds of power failure, and the LED will emit white light, and the sound is louder than the general buzzer. Much bigger.
How to turn off the buzzer:
Press and hold the release button for more than 2 seconds, the JHE42B_S Finder turns off the sound.
The JHE42B_S 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 JHE42B_S 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).

- Batteries should NEVER be left unattended while charging.
- Be absolutely sure that the Lithium Polymer charger settings are correct for the battery pack being charged – both voltage and current settings.
- Lithium Polymer must be CHARGED and STORED in a fire-safe container like a Lipo Sack.
- Do not charge batteries near flammable items or liquids.
- Keep a dry fire extinguisher nearby or a large bucket of dry sand, which is a cheap and effective extinguisher.
- Never charge inside an automobile even when parked.
- KEEP BATTERIES AWAY from children and pets at ALL times.
- Never discharge below 3.5V per cell as it may cause permanent damage and void warranty
- Battery may explode if damaged or disposed of in fire
- Never leave batteries inside a car on a hot day or any other place where temperature may exceed 140F / 60C.
- Although environmentally friendly, lithium polymer cells must be FULLY discharged before disposal. Use a resistor setup (light bulbs, for example) to accomplish this, to avoid the possibility of a short-induced fire after disposal.
- Immediately discharge damaged batteries at 1/2 C rate and dispose
- Do not put the loose cells in a pocket, bag, or drawer where they could short-circuit against other items, or the battery tabs could be pressed against each other.
- Take care that the cells are not punctured, especially by metallic objects like hobby knives.
- If the electrolyte in the cells should get on your skin, thoroughly wash with soap and water. If in the eyes, rinse thoroughly with cool water. Immediately seek medical attention for this, or for burns.
