4. Setup

Follow these steps to set up your OQIMAX Bluetooth 5.3 Audio Adapter.

Figure 4.1: Basic Setup Steps. This image visually guides the user through the three fundamental steps: plugging in the audio cable, pairing with a Bluetooth device, and playing/controlling music.

1. Power Connection: Connect the provided Type-C data cable to the adapter's Type-C port and the other end to a USB power source (e.g., wall adapter, computer USB port). The device will power on automatically.
2. Select Mode: Determine whether you need to transmit (TX) or receive (RX) audio. Slide the TX/RX switch on the adapter to the desired mode.
3. Connect Audio Cables:
   • For TX Mode: Connect the adapter to your non-Bluetooth audio source (e.g., TV, PC, MP3 player) using the appropriate RCA or AUX cable.
   • For RX Mode: Connect the adapter to your non-Bluetooth audio output device (e.g., wired speaker, home stereo, wired headphones) using the appropriate RCA or AUX cable.
4. Pairing: The adapter will automatically enter pairing mode. On your Bluetooth-enabled device (e.g., smartphone, Bluetooth headphones), search for and select "OQIMAX BT Adapter" (or similar name) from the list of available Bluetooth devices to connect.

5. Operating Modes

The OQIMAX Bluetooth 5.3 Audio Adapter supports two primary operating modes: Transmitter (TX) and Receiver (RX).

Figure 5.1: Wide Compatibility in TX and RX Modes. This image illustrates the diverse range of devices compatible with the adapter in both Transmitter (TX) mode (e.g., MP3 Player, TV, Desktop connecting to Headset, Bluetooth audio) and Receiver (RX) mode (e.g., Car Audio System, Amplifier connecting to Smartphone, Laptop).

5.1. Transmitter (TX) Mode

In TX mode, the adapter converts audio from non-Bluetooth devices (like TVs, PCs, MP3 players) into a Bluetooth signal, which can then be wirelessly transmitted to Bluetooth headphones or speakers.

1. Set the TX/RX switch to TX.
2. Connect the adapter's audio input (RCA or AUX) to the audio output of your non-Bluetooth device (e.g., TV, desktop computer).
3. Ensure your Bluetooth headphones or speaker are in pairing mode.
4. The adapter will automatically search for and connect to nearby Bluetooth receiving devices. Once connected, audio from your source device will play through your Bluetooth headphones/speakers.

Figure 5.2: TX Mode Application. This image demonstrates a common use case for TX mode, where a user is watching television and listening to the audio wirelessly through Bluetooth headphones, facilitated by the OQIMAX adapter.

5.2. Receiver (RX) Mode

In RX mode, the adapter receives Bluetooth audio signals from your smartphone, tablet, or laptop and outputs them to wired audio devices such as home stereo systems, car audio systems, or wired headphones.

1. Set the TX/RX switch to RX.
2. Connect the adapter's audio output (RCA or AUX) to the audio input of your wired speaker, amplifier, or car stereo.
3. On your Bluetooth-enabled device (e.g., smartphone), enable Bluetooth and search for "OQIMAX BT Adapter" (or similar name) to pair.
4. Once connected, you can stream audio wirelessly from your phone to your wired audio system.

6. Dual Connection

The OQIMAX Bluetooth 5.3 Audio Adapter supports connecting to two devices simultaneously in both TX and RX modes.

Figure 6.1: Dual Device Connection. This image illustrates the process of connecting two Bluetooth devices (e.g., a smartphone and a tablet) to the OQIMAX adapter, showing the steps to connect the first device and then use the A/B button to search and connect the second device.

Steps for Dual Connection:

1. Connect the first Bluetooth device (Device A) to the adapter as described in the Setup or Operating Modes sections.
2. After Device A is successfully connected, briefly press the A/B button on the adapter. This will put the adapter back into pairing mode to search for the second device.
3. Enable Bluetooth on your second device (Device B) and select "OQIMAX BT Adapter" (or similar name) from the list of available devices.
4. Once both devices are connected, you can switch between them or play audio from either device.

7. Maintenance

To ensure the longevity and optimal performance of your OQIMAX Bluetooth 5.3 Audio Adapter, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the surface of the device. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.
• Storage: Store the adapter in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
• Handling: Avoid dropping the device or subjecting it to strong impacts. Do not attempt to disassemble or modify the adapter, as this will void the warranty and may cause damage.
• Cable Care: Handle cables gently. Avoid bending or twisting them excessively, especially near the connectors, to prevent internal wire damage.

8. Troubleshooting

If you encounter issues with your OQIMAX Bluetooth 5.3 Audio Adapter, please refer to the following common problems and their solutions:

• Device not powering on:
  • Ensure the Type-C data cable is securely connected to both the adapter and a working USB power source.
  • Try a different USB power adapter or USB port.
• Cannot pair with a Bluetooth device:
  • Make sure the adapter is in the correct TX or RX mode.
  • Ensure your Bluetooth device is in pairing mode and within the 10-meter range of the adapter.
  • Clear the Bluetooth pairing history on your device and try pairing again.
  • Restart both the adapter (by unplugging and replugging the power) and your Bluetooth device.
• No sound or poor sound quality:
  • Check that all audio cables (RCA/AUX) are securely connected to the correct input/output ports on both the adapter and your audio device.
  • Verify that the adapter is in the correct TX/RX mode for your setup.
  • Adjust the volume on both the adapter and your connected audio device/headphones.
  • Ensure there are no obstacles between the adapter and the connected Bluetooth device that might interfere with the signal.
  • If experiencing latency, ensure your connected devices support low-latency codecs (though this adapter's primary focus is on stable connection, not specific low-latency codecs beyond Bluetooth 5.3's general improvements).
• Dual connection issues:
  • Ensure the first device is fully connected before attempting to pair the second.
  • Press the A/B button briefly to initiate the search for the second device.
  • Some devices may have compatibility limitations with dual connections. Try connecting one device at a time to isolate the issue.
