Notice: The microphone is very sensitive; do not drop, knock, or subject it to strong shock. If the microphone is placed near the speaker, it may produce whistling. In such cases, position the microphone farther away from the speaker or reduce the speaker volume. Switching the pickup mode may produce noise. The battery indicator on the microphone lights up briefly when powered on and then turns off automatically to save battery power and prevent interference with video recording. Please check the switch to confirm it is properly engaged, and turn off the microphone when not in use. With sufficient battery, the indicator flashes once upon powering on. During use, if the power light illuminates steadily, this indicates low battery. The microphone can still operate for one to two hours under these conditions, but replace the battery promptly.
