Notice: The microphone is very sensitive; avoid dropping, knocking, or subjecting it to strong shock. If the microphone is placed near the speaker, feedback may occur. To prevent this, position the microphone away from the speaker or reduce the speaker volume. Changing the pickup mode switch settings may produce noise. The battery indicator on the microphone lights up briefly when powered on and then turns off to conserve battery power and prevent interference with video recording. Always check the switch to confirm it is properly engaged, and turn off the microphone when not in use. When the battery is low, the power light will flash once upon turning on. During use, if the power light illuminates steadily, the battery is low but can still operate for one to two hours. Replace the battery promptly under these conditions.
