Operating Instructions
Transmitter (TX) Mode
In TX mode, the ABCD54F sends audio from your non-Bluetooth device to Bluetooth headphones or speakers.
- Ensure the TX/RX switch is set to TX.
- Connect the ABCD54F to your audio source (e.g., TV, PC) using the appropriate cable (Optical, AUX, or RCA). Select the correct input type using the AUX/OPT button.
- Press and hold the Bluetooth pairing button on the ABCD54F until the TX LED flashes rapidly, indicating pairing mode.
- Put your Bluetooth headphones or speakers into pairing mode. Refer to their respective manuals for instructions.
- The devices will automatically connect. The TX LED on the ABCD54F will turn solid blue once connected.
- Dual Device Streaming: The ABCD54F can stream to two Bluetooth devices simultaneously. After connecting the first device, put the second device into pairing mode and press the Bluetooth pairing button on the ABCD54F again to connect it.

Receiver (RX) Mode
In RX mode, the ABCD54F receives audio from your Bluetooth-enabled device and outputs it to a non-Bluetooth audio system.
- Ensure the TX/RX switch is set to RX.
- Connect the ABCD54F to your audio system (e.g., stereo, wired speakers) using the appropriate cable (Optical, AUX, or RCA). Select the correct output type using the AUX/OPT button.
- The RX LED on the ABCD54F will flash rapidly, indicating it is in pairing mode.
- On your Bluetooth-enabled device (smartphone, tablet), go to Bluetooth settings and search for "Aluratek ABCD54F" (or similar). Select it to pair.
- Once connected, the RX LED on the ABCD54F will turn solid blue. You can now stream audio from your device to your audio system.

Volume Control
The volume buttons (+/-) on the Aluratek ABCD54F primarily control the output volume when the device is in Receiver (RX) mode. When in Transmitter (TX) mode, the volume control functionality may be limited or non-existent, as the volume is typically controlled by the connected receiving device (headphones/speakers) or the audio source (TV/PC).
