6. Troubleshooting
If you encounter issues with your YF79 microphone, please refer to the following common solutions:
| Problem | Possible Solution |
|---|---|
| Microphone does not power on | Ensure the battery is charged. Connect the USB charging cable and allow it to charge for at least 30 minutes before attempting to power on again. |
| No sound from the microphone | Check the microphone's volume level. Ensure it is properly connected via Bluetooth or auxiliary cable. Verify the connected device's volume is also turned up. |
| Bluetooth connection fails or is unstable | Ensure the microphone is in pairing mode. Turn off and on Bluetooth on your device, then try re-pairing. Move closer to the microphone to reduce interference. Ensure no other devices are actively connected to the microphone. |
| Poor sound quality or distortion | Check for obstructions around the microphone head. Ensure the microphone is not too close to the speaker, which can cause feedback. Adjust the echo level. Ensure the audio source is of good quality. |
| TWS (Duet Singing) pairing issues | Ensure only one microphone is initially paired to the phone. Follow the TWS pairing steps carefully (Section 4.3). Make sure both microphones are within close proximity during pairing. |
