6.1. Switching Between Transmitter (TX) and Receiver (RX) Modes

The adapter features a physical switch to change between modes. Slide the switch to the desired mode (TX for Transmitter, RX for Receiver) before connecting or pairing.

6.2. 송신기 모드(TX)

In TX mode, the adapter transmits audio from a non-Bluetooth device to Bluetooth headphones or speakers.

1. Ensure the adapter is switched to 송신 모드.
2. Connect the adapter's 3.5mm audio socket to the audio output port of your non-Bluetooth device (e.g., TV, home stereo system, CD player, PC) using the provided 3.5mm audio cable or 3.5mm to 2RCA cable.
3. Turn on the adapter. The indicator light will flash, indicating it is searching for Bluetooth devices.
4. Bluetooth 헤드폰이나 스피커를 페어링 모드로 전환하세요.
5. The adapter will automatically search for and connect to nearby Bluetooth audio devices. Once connected, the indicator light will change to a steady blue.

This diagram shows the adapter in Transmitter (TX) mode, connecting a non-Bluetooth audio source like a TV, computer, or MP3 player to Bluetooth headphones or a Bluetooth speaker.

메모: The adapter supports pairing with one Bluetooth receiver (headphones or speaker) at a time in TX mode.

6.3. 수신 모드(RX)

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

1. Ensure the adapter is switched to 수신 모드.
2. Connect the adapter's 3.5mm audio socket to the audio input port of your wired stereo, speakers, or headphones using the provided 3.5mm audio cable or 3.5mm to 2RCA cable.
3. Turn on the adapter. The indicator light will flash, indicating it is in pairing mode.
4. On your Bluetooth-enabled device (e.g., phone, tablet, computer), enable Bluetooth and search for new devices. Select "VR-NK321" (or similar name) from the list of available devices to pair.
5. Once connected, the indicator light will change to a steady blue. You can now stream audio from your Bluetooth device to your wired audio system.

This diagram illustrates the adapter in Receiver (RX) mode, enabling a wired stereo system, speakers, or headphones to receive audio wirelessly from a Bluetooth-enabled phone, tablet, or computer.

7. 문제 해결

If you encounter issues with your VR-robot Bluetooth adapter, refer to the following common solutions:

• 장치가 켜지지 않음: 기기가 완전히 충전되었는지 확인하세요. Micro USB 케이블을 사용하여 기기를 전원에 연결하세요.
• Bluetooth 장치와 페어링할 수 없습니다.
  • 사용 목적에 맞게 어댑터가 올바른 모드(TX 또는 RX)인지 확인하세요.
  • Make sure the adapter and the target Bluetooth device are within close proximity (within 33 feet or 10 meters).
  • Put both devices into pairing mode.
  • Turn off other Bluetooth devices nearby to prevent interference or unintended connections.
  • Restart both the adapter and the Bluetooth device you are trying to pair with.
• 오디오가 나오지 않거나 오디오 품질이 좋지 않음:
  • Check all cable connections to ensure they are secure and correctly inserted into the audio input/output ports.
  • Verify that the volume levels on both the adapter and the connected audio devices are appropriately set.
  • Ensure the adapter is fully charged. Low battery can affect performance.
  • Reduce the distance between the adapter and the connected Bluetooth device, and remove any obstacles that might cause interference.
• Short working range: Bluetooth range can be affected by physical obstructions (walls, furniture) and electromagnetic interference. Try to use the device in an open area with a clear line of sight between the adapter and the connected Bluetooth device.
