Operating Instructions

TX Mode (Transmitter)

In TX mode, the BR08 transmits audio from a non-Bluetooth source to Bluetooth receiving devices (e.g., headphones, speakers).

Switch the device to TX mode. The Bluetooth prompt light will illuminate.
Connect the BR08's 3.5mm audio jack to the audio output port of your non-Bluetooth device (e.g., desktop computer, television, CD player).
Ensure your Bluetooth headphones or speakers are in pairing mode.
The BR08 will automatically search for and connect to nearby Bluetooth receiving devices. The Bluetooth indicator light(s) will show connection status.
Once connected, audio from your source device will be transmitted to your Bluetooth headphones/speakers.

RX Mode (Receiver)

In RX mode, the BR08 receives Bluetooth audio from your phone/tablet/laptop and outputs it to a non-Bluetooth audio system (e.g., car audio, wired speakers, wired headphones).

Switch the device to RX mode. The Bluetooth prompt light will illuminate.
Connect the BR08's 3.5mm audio jack to the AUX input port of your non-Bluetooth audio system (e.g., amplifier speaker, car audio, Bluetooth speaker, wired headset).
Enable Bluetooth on your mobile phone, iPad, or laptop and search for "BR08" in the list of available devices.
Select "BR08" to pair. The Bluetooth indicator light(s) will show connection status.
Once connected, you can stream audio from your Bluetooth device to your connected audio system.

Connecting Two Bluetooth Devices Simultaneously

The BR08 supports connecting to two Bluetooth devices at the same time in both RX and TX modes.

Connect the first Bluetooth device as described in the TX or RX mode instructions.
Once the first device is connected, put the second Bluetooth device into pairing mode.
On your source device (for RX mode) or the BR08 (for TX mode), search for the second device's pairing name and connect.
Both Bluetooth 1 and Bluetooth 2 indicators will be lit when two devices are connected.
