How to Use Both Dongles Together as a Tandem
The two dongles can be used in a tandem as a Bluetooth range "extender" for 2 other already-paired devices.
Step 1: Power on the RX dongle
Please ONLY power on the RX dongle for now; leave the TX dongle OFF.
Step 2: Get the RX dongle into Bluetooth Pairing Mode, and pair it with the device that's "transmitting" the audio.
This can be a Mobile Device or a Bluetooth TV... or simply another Bluetooth Transmitter.
Step 3: Get the TX dongle in to Bluetooth Pairing Mode, and pair it with the device that's "receiving" the audio.
This is likely a Bluetooth headphone/speaker, or another Bluetooth Receiver. Please make sure you only get to this step AFTER step 2 has been completed.
Step 4: Connect the two dongles to each other.
Take the 3.5mm AUX connector that we provided, plug one end into the 3.5mm AUX port on the TX dongle, and the other end into the 3.5mm AUX port on the RX dongle.
