2. The microphone whistles during use. This may be caused by the hand covering the microphone head or the microphone being too close to the loudspeaker. The correct solution is to first lower the volume and pull off the loudspeaker distance, try to avoid the microphone and loudspeaker, and then adjust to the appropriate volume.
3. The microphone is high-sensitivity audio equipment. It must be handled with care, and avoid falling from high places. Impact may cause the microphone sensitivity to decrease or even damage.
4. Do not blow the microphone or blow the head to test the sound with your hand. The correct method of audition is to point the microphone to speak in normal tone.
5. The push-pull key to the microphone must pay attention to moderate force, push and pull in place. If you find that there is a lot of noise during use, it may be caused by the fact that the switch key is not pushed or pulled in place or the touch is not good. The correct method is to push and pull the switch again. If contact is bad, it should be repaired as soon as possible.
6. The conference microphone or wireless microphone will not be used for a long period of time. The battery should be removed and then installed when it is used. If sound intermittent occurs during use, it may be due to insufficient battery power. Replace the battery in time.
7. When not in use, store the microphone in a dry and clean place. Avoid storing and using in places with high temperature and humidity, so as not to affect the sensitivity and sound of the microphone.
