1. Correctly install and remove the connecting cable and microphone. Insert the XLR plug (commonly known as a Cannon plug) into the microphone, rotate the plug so that the latch on top aligns with the slot on the microphone, and then push the plug into the microphone until the latch locks into place; When separating the microphone from the connecting cable, hold the plug, simultaneously press the latch, and then pull the plug out of the microphone. Never forcefully connect or disconnect without aligning or pressing the latch.
2. If the microphone produces a "howling" sound during use, this may be because the hand is covering the microphone head or the microphone is too close to the loudspeaker. The correct solution is to: first lower the volume, increase the distance from the loudspeaker, avoid the microphone and loudspeaker facing each other as much as possible, and then adjust to a suitable volume.
3. Microphones are highly sensitive audio devices. Handle them gently and avoid dropping them from a height. Impacts may reduce the microphone's sensitivity or even damage it.
4. Do not blow forcefully into the microphone or tap its head to test the sound. The correct way to test the sound is to speak into the microphone in a normal tone.
5. When pushing and pulling the microphone's on/off switch, pay attention to using moderate force and ensuring it is fully engaged. If excessive noise is detected during use, it may be because the switch is not fully engaged or the contact is poor. The correct procedure is to push and pull the switch again. If the contact is poor, repairs should be made promptly.
