Note:
Not all cameras have a microphone input. Verify this with your camera manufacturer. Many cameras have headphone, remote control, and other ports that look similar to a microphone input. Make sure that you are using the correct one.
No need to install battery when using the microphone with a smartphone or a laptop. Install battery in right polarities when using the microphone with a camera or other devices (audio recorder, amplifier, etc.).
