Notice: The microphone is very sensitive; avoid dropping, knocking, or subjecting it to strong shock. If the microphone is placed near a speaker, feedback may occur. To prevent this, position the microphone 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 conserve power and prevent interference with video recording. Always check the switch to ensure it is turned off when the microphone is not in use. When the battery is low, the power light will flash once upon turning on, and during use, the power light may illuminate, indicating that the battery is running low. The microphone can still operate for one to two hours under these conditions, but replace the battery promptly.
