Operating Modes

The LAICOMEIN Bluetooth adapter supports two primary operating modes: Transmitter (TX) and Receiver (RX). Use the Mode Switch (RX / TX) on the side of the device to select the desired mode.

TX Mode (Transmitter)

In TX mode, the device transmits audio from a non-Bluetooth source (e.g., TV, MP3 player, gaming console, airplane entertainment system) to your Bluetooth headphones or speakers.

1. Set the Mode Switch to TX.
2. Connect the device to your non-Bluetooth audio source using the 3.5mm audio cable. For TVs or other devices with RCA outputs, use the provided RCA audio cable. For airplane entertainment systems, use the dual 3.5mm male to female adapter if needed.
3. Ensure your Bluetooth headphones or speakers are in pairing mode.
4. Press the Pairing Button on the LAICOMEIN adapter to initiate pairing. The Device 1 Status Light will flash, indicating it's searching for devices.
5. Once paired, the Device 1 Status Light will turn solid. You can now enjoy wireless audio.
6. Dual Pairing (TX Mode): To connect a second pair of Bluetooth headphones/speakers, ensure the first device is connected, then put the second device into pairing mode and press the Pairing Button again. The Device 2 Status Light will illuminate when the second device is connected.

Note: For best performance in TX mode, turn off nearby Bluetooth devices (e.g., phones/iPads) when pairing to avoid interference.

2. Connect the device to your non-Bluetooth audio system (e.g., car stereo AUX input, home stereo AUX input) using the 3.5mm audio cable.
3. Enable Bluetooth on your smartphone, tablet, or other audio source and search for "LAICOMEIN B110" (or similar device name) in the list of available Bluetooth devices.
