5. Operating Modes

5.1 Transmitter Mode (TX)

In Transmitter Mode, the device sends audio wirelessly from a non-Bluetooth source to Bluetooth headphones or speakers.

Connecting to TV/PC (Audio Cable)

Connect the device to your TV, PC, or MP3 player's 3.5mm audio output using the provided 3.5mm audio cable. Ensure your Bluetooth headphones or speakers are in pairing mode. The adapter will automatically search for and connect to your Bluetooth audio device. Keep the adapter close to the paired device for a better connection.

Connecting to PC (USB Data Cable)

For PC audio transmission, you can directly connect the device to your PC's USB port using the USB charging data cable. In this setup, a 3.5mm audio cable is not required. Note that when using the USB cable for audio transmission to a computer, the computer's system volume cannot be adjusted; only the volume of the playing software can be controlled.

5.2 Receiver Mode (RX)

In Receiver Mode, the device receives audio from a Bluetooth-enabled source (like a smartphone or tablet) and outputs it to a non-Bluetooth audio device (like wired headphones or a car speaker system).

Connect the device to your wired headphones, car speaker system, or home stereo using the 3.5mm audio cable. Enable Bluetooth on your smartphone or tablet and search for the LENDAWAY device to pair. Once connected, audio from your Bluetooth source will play through your wired audio system.

6. Important Notes & Troubleshooting

• Pairing Issues: If you cannot connect the Bluetooth adapter to your Bluetooth headphones/earbuds/earphones the first time, ensure your device is not connected to any other device while pairing. Keep the devices close to each other (within 1 meter) during pairing.
• Sound Quality: The Bluetooth receiver/transmitter is equipped with advanced decoders. If you encounter sound quality issues, double-check the audio source for optimal performance.
• Latency/Audio Lag: This Bluetooth adapter is mainly used for Bluetooth transfer between headphones and common audio equipment. Most instruments like guitars require 2.4G transfer to achieve audio signal synchronization, so please do not use it for music performance where real-time audio is critical.
• TV Compatibility: For TV use, please first ensure your TV has a 3.5mm AUX output.
• Charging & Noise: The common ground current noise may cause noise. It is suggested not to use the device while charging to avoid current noise. It's better to wait until it's fully charged before using it.
• Single Device Connection: Only one device can be paired at a time; it does not transmit to multiple devices simultaneously.
• Operating Range: The distance between the Bluetooth adapter and your Bluetooth device should be within 50 feet (15m) in open areas, or 33ft (10m) with obstacles.
• Charging Safety: The charging standard of the product is 5V1A. Do not use a high current adapter to charge the product.
• Mode Confusion: Pay attention to whether you want to receive (RX) or transmit (TX) when you use it. There will be no sound if you connect incorrectly.
