Before turning on the wireless microphone, you need to ensure that the microphone is equipped with a battery and the battery is sufficient, and then press the power button on the microphone, which is generally a circular button, until the microphone display screen lights up or you can start using the prompt tone. In the process of use, it is necessary to pay attention to the distance between the microphone and the receiver and whether the signal is stable, so as not to affect the sound quality and transmission effect. Turn off the microphone immediately after use to save power and extend battery life.
