Operating Modes

Transmitter (TX) Mode

In TX mode, the adapter converts non-Bluetooth audio sources into Bluetooth signals. This allows you to wirelessly stream audio from devices like TVs, computers, MP3/MP4 players, or gym equipment to Bluetooth headphones or speakers.

2. Connect the adapter to the audio output port (e.g., 3.5mm AUX) of your non-Bluetooth device using the provided 3.5mm audio cable.
3. Ensure your Bluetooth headphones or speakers are in pairing mode.
4. The adapter will automatically search for and connect to nearby Bluetooth audio devices. Once connected, the indicator light will confirm.

Receiver (RX) Mode

In RX mode, the adapter receives Bluetooth audio signals from your smartphone, tablet, or laptop and outputs them to non-Bluetooth audio systems like car stereos, wired speakers, or home amplifiers.

1. Switch the device to RX mode.
2. Connect the adapter to the audio input port (e.g., 3.5mm AUX) of your non-Bluetooth audio system using the provided 3.5mm audio cable.
3. On your Bluetooth-enabled device (e.g., smartphone), search for "C86S" (or similar device name) in the Bluetooth settings and pair.
4. Once connected, audio from your Bluetooth device will play through the connected audio system.
