The 1Mii B06T2 operates in two modes: Transmitter (TX) and Receiver (RX). Use the TX/RX switch on the side of the device to select the desired mode before connecting.

• TX Mode: Transmits audio from a non-Bluetooth device (e.g., TV, PC) to Bluetooth headphones or speakers.
• RX Mode: Receives audio from a Bluetooth-enabled device (e.g., smartphone, tablet) and outputs it to a wired audio system (e.g., home stereo, car stereo).

3. Operating Instructions

Transmitter Mode (TX)

Use TX mode to add Bluetooth transmission capabilities to devices without built-in Bluetooth.

1. Switch the B06T2 to TX mode.
2. Connect the 3.5mm AUX jack of the B06T2 to the audio output port (e.g., headphone jack) of your non-Bluetooth device (TV, PC, MP3 player). Alternatively, connect the Type-C port to your PC for USB audio input.
3. Press and hold the Power/Pairing button for 2 seconds to turn on the device and enter pairing mode. The LED indicator will flash red and blue alternately.
4. Put your Bluetooth headphones or speaker into pairing mode.
5. Place the B06T2 and your Bluetooth audio device close to each other. Once paired, the LED indicator will stop flashing and remain solid blue (or another color depending on the codec).

Understanding aptX Low Latency and aptX HD

The 1Mii B06T2 supports advanced audio codecs for superior sound quality and reduced latency:

• aptX Low Latency (aptX-LL): Provides ultra-low latency (under 36ms) for perfect audio-visual synchronization, ideal for watching TV, movies, or gaming. For aptX-LL to function, both the B06T2 and your receiving/transmitting device (e.g., headphones) must support aptX-LL.
• aptX HD: Delivers high-definition audio quality (24-bit/48kHz) for an immersive listening experience. For aptX HD to function, both the B06T2 and your receiving/transmitting device must support aptX HD.

4. Maintenance

To ensure the longevity and optimal performance of your 1Mii B06T2, follow these maintenance guidelines:

• Keep the device dry. Moisture can damage internal circuits.
• Avoid extreme temperatures. High temperatures can shorten the life of electronic devices.
• Do not expose the device to direct sunlight for extended periods.
• Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Store the device in a cool, dry place when not in use.

5. Troubleshooting

If you encounter issues with your 1Mii B06T2, try the following solutions:

• Device not pairing:
  1. Ensure the B06T2 is in the correct TX or RX mode.
  2. Make sure both the B06T2 and your target audio device are in pairing mode (LED flashing red and blue alternately).
  3. Bring the devices closer together.
  4. Press and hold the RESET button on the B06T2 for 2 seconds to clear previous pairing history, then try pairing again.
• No sound or poor sound quality:
  1. Check all cable connections (3.5mm AUX, USB-C). Ensure they are securely plugged in.
  2. Verify that the volume on both the B06T2 and the connected audio device is turned up.
  3. Ensure the correct audio input/output is selected on your external device (e.g., AUX input on a speaker).
  4. If experiencing noise, avoid connecting the power cord to the TV for charging while in use, as this can generate current noise. Use a separate USB power adapter.
• High latency (audio delay):
  1. For ultra-low latency, ensure both the B06T2 and your Bluetooth headphones/speaker support aptX Low Latency (aptX-LL).
  2. Reduce the distance between the B06T2 and the connected Bluetooth device.
  3. Minimize obstacles between the devices.
• Cannot connect to Airpods Max or Airpods Pro 2nd generation: The device is compatible with Airpods but not with Airpods Max or Airpods Pro 2nd generation.
• Not suitable for musical instruments: The B06T2 cannot be used as an instrument transmitter for electric guitars or keyboards due to potential latency issues.
