• No Power: Ensure the device is properly connected to a power source (B03) or fully charged (ML100). Try a different USB port or power adapter.
• Cannot Pair:
  • Ensure the device is in the correct mode (TX for B03 transmitting, RX for B03 receiving, ML100 is always RX).
  • Make sure your Bluetooth device (headphones, phone, etc.) is in pairing mode.
  • Clear the pairing list on the 1Mii device (ML100: press and hold +/- for 10s; B03: refer to specific reset instructions in its full manual if available, otherwise power cycle).
  • Move the devices closer to each other.
  • Restart both the 1Mii device and your Bluetooth device.
• No Sound/Poor Sound Quality:
  • Check all audio cables are securely connected to the correct input/output ports.
  • Ensure the correct input source is selected on your TV/stereo system.
  • For B03 optical connection, ensure your TV's audio output format is set to PCM (Dolby/DTS are not supported).
  • Adjust volume levels on both the 1Mii device and your connected audio system/Bluetooth device.
  • Ensure there are no significant obstructions between the 1Mii device and your Bluetooth headphones/speakers (for wireless connections).
• Intermittent Connection:
  • Reduce the distance between the 1Mii device and the connected Bluetooth device.
  • Minimize interference from other wireless devices (Wi-Fi routers, microwaves, etc.).
