The Naroote USB Bluetooth 5.0 Transmitter Receiver is designed for simple plug-and-play operation.

1. Power On: Insert the USB-A connector of the device into any standard USB port (e.g., on a PC, car charger, USB wall adapter, or speaker with a USB port). The device will automatically power on.
2. Mode Selection: The device will automatically enter pairing mode. The LED indicator will flash, indicating it is ready to connect.
3. Connect Audio Cable: Depending on whether you are using Transmitter (TX) or Receiver (RX) mode, connect the 3.5mm audio cable to the device's 3.5mm port and to your audio source (for TX mode) or audio output device (for RX mode).

4. Operating Modes

The device supports both Transmitter (TX) and Receiver (RX) modes. The mode is typically determined by how the 3.5mm audio cable is connected and the device it's paired with. The central button on the device can be used to switch between modes or initiate pairing.

4.1 Transmitter (TX) Mode

In TX mode, the device sends audio wirelessly from a non-Bluetooth audio source (like a TV, PC, or MP3 player) to a Bluetooth-enabled receiving device (like Bluetooth headphones or speakers).

1. Connect Audio Source: Plug one end of the 3.5mm audio cable into the device's 3.5mm port and the other end into the audio output (e.g., headphone jack) of your non-Bluetooth audio source.
2. Power On: Insert the USB connector into a power source (e.g., USB port on TV, PC, or a USB charger). The device will power on and the "TRANSMIT" indicator (blue light) should illuminate or flash.
3. Pairing: Put your Bluetooth headphones or speaker into pairing mode. The Naroote device will automatically search for and connect to nearby Bluetooth receiving devices.
4. Audio Playback: Once connected, audio from your source device will be transmitted wirelessly to your Bluetooth headphones or speaker.

4.2 Receiver (RX) Mode

In RX mode, the device receives audio wirelessly from a Bluetooth-enabled source (like a smartphone or tablet) and outputs it to a non-Bluetooth audio system (like car stereo, home stereo, or wired headphones).

1. Connect Audio Output: Plug one end of the 3.5mm audio cable into the device's 3.5mm port and the other end into the auxiliary input (AUX-in) of your non-Bluetooth audio system (e.g., car stereo, home speaker).
2. Power On: Insert the USB connector into a power source (e.g., car USB port, USB wall adapter). The device will power on and the "RECEIVE" indicator (red light) should illuminate or flash.
3. Pairing: On your smartphone or tablet, enable Bluetooth and search for the Naroote device (it may appear as "YET-TR6" or similar). Select it to pair.
4. Audio Playback: Once connected, audio from your smartphone will be received wirelessly by the Naroote device and played through your connected audio system.
