Notice: The microphone is very sensitive; do not drop, knock, or subject it to strong shock. If the microphone is placed close to a speaker, feedback may occur. To prevent this, position the microphone away from the speaker or reduce the speaker volume. Switching between pickup modes may produce noise. The battery indicator on the microphone lights up briefly when powered on and then turns off to conserve power and prevent light interference with video recording. Always check the switch to confirm it is properly turned off when the microphone is not in use. When the battery indicator flashes once upon turning on, or if the power light illuminates during use, this indicates low battery. The microphone can still operate for one to two hours under these conditions, but replace the battery promptly.
