Quick Guide for 1Mii B06TX

This document provides troubleshooting steps for the 1Mii B06TX Bluetooth Transmitter. It covers connection procedures, audio lag resolution, sound troubleshooting, and device reset instructions.

Connecting Bluetooth Headphones or Speakers

To ensure a successful connection, follow these steps:

  • Turn off Bluetooth on nearby phones, PCs, and TVs to avoid interference.
  • Connect the 1Mii B06TX to a power adapter and press the power button to turn it on.
  • The device will enter pairing mode automatically. If it does not, press the Bluetooth button.
  • Ensure the Bluetooth indicator flashes red and blue.
  • Set your headphones to pairing mode.
  • Plug only one audio cable from the 1Mii B06TX to the audio output of your TV or source device.

Note: The 1Mii B06TX is a transmitter only and does not support being paired with phones, tablets, or PCs as a receiver.

Troubleshooting Audio Lag

If you experience audio delay (70-200ms):

  • Ensure your receiving device (headphones/speaker) supports aptX Low Latency.
  • If your device supports both aptX Low Latency and aptX HD, you can switch modes by double-pressing the power button.
  • AptX Low Latency mode is indicated by a blue light; aptX HD mode is indicated by a green light.

Resolving Sound Issues

If you have no sound or poor sound quality:

  • Check Audio Format: When using Optical or Coaxial cables, ensure the TV audio format is set to PCM. Dolby is not supported.
  • Cable Connections: Ensure only one audio cable is plugged into the transmitter at a time.
  • Audio Interface: Verify that the cable is plugged into the correct AUDIO OUTPUT port on your TV.
  • Try Alternative Cables: If the volume buttons do not work while using an optical cable, switch to an AUX 3.5mm or RCA audio cable.

Reset Procedure

If the above steps do not resolve your sound issues, perform a factory reset:

  • Press and hold both the Bluetooth button and the power button simultaneously for about 5 seconds.
  • The device will flash blue light twice, then enter pairing mode with red and blue lights flashing alternately.
  • Re-pair your device.

Practical help

Common problems

No sound or bad sound quality

Ensure TV audio format is set to PCM (Dolby not supported), check that only one audio cable is connected, and verify the cable is in the AUDIO OUTPUT port.

Audio lag/delay

Ensure the receiving headphones/speaker support aptX Low Latency. If the device supports both aptX LL and aptX HD, double-press the power button to switch to aptX LL mode (blue light).

Volume buttons not working

Before use

  • Turn off Bluetooth on nearby devices (phones, PCs, TVs) to prevent interference.

  • Ensure only one audio cable is connected to the transmitter.
  • Verify the receiving device is in pairing mode.
