4.1 Receiver Mode (RX)

In RX mode, the adapter receives audio wirelessly from a Bluetooth-enabled device (e.g., smartphone, tablet, laptop) and outputs it to a non-Bluetooth audio device (e.g., car stereo, wired headphones, wired speaker).

1. Switch the adapter to RX mode using the Transmitter/Receiver switch.
2. Connect the adapter's Aux In/Out port to the audio input of your non-Bluetooth device (e.g., car stereo AUX-in, headphone jack) using a 3.5mm audio cable (not included).
3. Power on the adapter. The indicator light will flash, indicating it is in pairing mode.
4. On your Bluetooth-enabled device, search for Bluetooth devices and select "OQIMAX Adapter" (or similar name) to pair.
5. Once paired, the indicator light will become solid. You can now play audio from your Bluetooth device, and it will be transmitted to your connected non-Bluetooth audio system.

4.2 Transmitter Mode (TX)

In TX mode, the adapter takes audio from a non-Bluetooth audio source (e.g., TV, computer, wired home stereo) and transmits it wirelessly to a Bluetooth audio device (e.g., Bluetooth headphones, Bluetooth speaker).

1. Switch the adapter to TX mode using the Transmitter/Receiver switch.
2. Connect the adapter's Aux In/Out port to the audio output of your non-Bluetooth source device (e.g., TV headphone jack, computer audio out) using a 3.5mm audio cable (not included).
3. Power on the adapter. The indicator light will flash, indicating it is in pairing mode.
4. Put your Bluetooth headphones or speaker into pairing mode.
5. The adapter will automatically search for and connect to nearby Bluetooth audio devices. Once paired, the indicator light will become solid. You can now listen to audio from your wired source on your Bluetooth audio device.

5. Hands-Free Calling

When the adapter is in RX mode and connected to your smartphone, you can use its built-in microphone and Multifunction Button for hands-free calling.

• Answer Call: Press the Multifunction Button once.
• End Call: Press the Multifunction Button once during a call.
• Reject Call: Press and hold the Multifunction Button for 2 seconds when a call comes in.
• Redial Last Number: Double-press the Multifunction Button.

6. Maintenance

• Keep the device dry. Avoid exposure to moisture or liquids.
• Do not attempt to disassemble or modify the device. This will void the warranty and may cause damage.
• Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Store the device in a cool, dry place when not in use.

7. Troubleshooting

• No Power: Ensure the device is fully charged. Connect it to a power source using the USB charging cable.
• Cannot Pair:
  • Ensure the adapter is in the correct mode (RX for receiving, TX for transmitting).
  • Make sure the adapter is in pairing mode (indicator light flashing).
  • Ensure the other device (smartphone, headphones) is also in pairing mode.
  • Move the devices closer together (within 33 feet / 10 meters) and ensure no major obstacles.
  • Turn off and on both devices, then try pairing again.
  • The adapter automatically reconnects to the last paired device. If you want to pair a new device, ensure the previous device's Bluetooth is off or out of range.
• No Audio:
  • Check that the 3.5mm audio cable is securely connected to both the adapter and the audio device.
  • Ensure the adapter is in the correct mode (RX or TX) for your setup.
  • Verify that both the adapter and the connected audio devices have their volumes turned up.
  • Confirm that the adapter is successfully paired and connected (solid indicator light).
• Poor Audio Quality / Intermittent Connection:
  • Ensure devices are within the optimal operating range (up to 33 feet / 10 meters) without significant physical obstructions (walls, doors, etc.).
  • Avoid interference from other wireless devices (Wi-Fi routers, other Bluetooth devices).
  • Ensure the adapter is fully charged. Low battery can affect performance.
