Press and hold the button on the side of the microphone for 2-3 seconds, then turn on the speaker. The microphone will connect automatically. When connected successfully, the microphone indicator light turns solid green, and the "Connect" indicator on the speaker display remains lit. How to improve sound quality: 1. Position the microphone within 6 inches of your mouth for clear and smooth audio. Excessive distance, such as when turning or tilting your head, may cause audio interruption or distortion. 2. Small adjustments to microphone placement and speaker distance can enhance sound quality. Test positioning in advance for optimal performance. 3. Ensure the front of the microphone faces your mouth directly to capture voice clearly and reduce background noise. 4. Avoid pointing the speaker toward the microphone to prevent feedback. The system may reduce certain frequencies to suppress noise, which can affect voice clarity. 5. For best results, do not place the speaker and wireless lapel microphone too close together to avoid audio delay. 6. To prevent feedback, always keep the speaker at least 20 inches away from the microphone.
