1. It may be out of power. Charge or replace the battery.
1. Maybe the microphone filter is not smooth, clean the microphone filter or clean the sound inlet hole.
3. There may be stains on the diaphragm of the microphone sensor. Open and clean the diaphragm.
4. Electrostatic interference may be caused by dust on the circuit board. Clean the circuit board with water or alcohol and air dry it.
5. It may be that the wire is welded or the wire is in poor contact. Re-solder or re-insert to remove possible problems.
6. The life of the capacitor is limited, and the change of the capacity of the capacitor will affect the filtering effect. Check the capacity of the capacitor and compare the normal data, and replace it.
7. The transmitter is faulty, possibly because the antenna or related capacitor resistance is damaged.
8. The signal may be unstable due to CPU fault, virtual welding, or input-output disconnection.
Maintenance risks, from simple to complex, reduce the chance of rollover.
solution
1, take a look at whether the contact is poor (whether the connection is successful or the wind problem);
2, if it is broken, try to repair (to the microphone site repair);
3, you can buy a new wireless microphone.
Wireless microphone, or wireless microphone, is a sound equipment that transmits sound signals, consisting of two parts, transmitter and receiver, usually called wireless microphone system.
