The wireless Bluetooth microphones are heavy-duty and well-built for high performance. If it is not working, there are a few things you need to check. Is the battery fully charged? Is it within the acceptable range of the voice amplifier unit?
When you turn on the Bluetooth microphone, the BLUE light should turn on. If it is not turning on, it may not connect with the amp. Make sure that the mic is sufficiently charged, or better, charge it for 3-4 hours. If after charging and the mic is still not working, it may be broken.
If the Bluetooth microphone is not pairing with the amp or cannot be recognized by the device, it is possible that the mic is broken. You can call our support for additional troubleshooting. If you need a replacement, you can purchase it separately from www.winbridgestore.com.
