4.1 Transmitter (TX) Mode
In TX mode, the LE505 transmits audio from a non-Bluetooth device (e.g., TV, PC, MP3 player) to Bluetooth headphones or speakers.
Image: A diagram illustrating how to connect the adapter in both Transmitter (TX) and Receiver (RX) modes to various audio devices.
- Slide the mode switch to 'TX'.
- Connect the 3.5mm audio cable from the LE505's 3.5mm interface to the audio output port (e.g., headphone jack) of your non-Bluetooth device (TV, PC, MP3/MP4 player).
- Turn on your Bluetooth headphones or speaker and set them to pairing mode.
- Press the 'A' pairing button on the LE505. The 'A' Bluetooth status light will flash, indicating it is searching for devices.
- Once paired, the 'A' Bluetooth status light will remain solid. Audio from your non-Bluetooth device will now play through your Bluetooth headphones/speaker.

Dual Link Function (TX Mode)
To connect a second pair of Bluetooth headphones or speaker:
- Ensure the first device is already paired (as per steps 1-5 above).
- Turn on the second Bluetooth headphones or speaker and set them to pairing mode.
- Press the 'B' pairing button on the LE505. The 'B' Bluetooth status light will flash.
- Once paired, the 'B' Bluetooth status light will remain solid. Both devices will now receive audio.
4.2 Receiver (RX) Mode
In RX mode, the LE505 receives audio from a Bluetooth-enabled device (e.g., smartphone, tablet) and outputs it to a non-Bluetooth audio system (e.g., wired headphones, car stereo, home speaker system).
Image: A diagram illustrating how to connect the adapter in both Transmitter (TX) and Receiver (RX) modes to various audio devices.
- Slide the mode switch to 'RX'.
- Connect the 3.5mm audio cable from the LE505's 3.5mm interface to the audio input port (e.g., AUX-in) of your non-Bluetooth audio system (wired headphones, car stereo, wired speakers).
- On your Bluetooth-enabled device (smartphone, tablet, Bluetooth laptop), search for Bluetooth devices and select 'LE505' from the list.
- Once paired, the 'A' Bluetooth status light on the LE505 will remain solid. Audio from your Bluetooth device will now play through your connected audio system.

5. Maintenance
- Keep the device dry. Avoid exposure to moisture or liquids.
- Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Store the device in a cool, dry place when not in use.
- Avoid extreme temperatures.
- Do not attempt to disassemble or repair the device yourself. This will void the warranty.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery. | Charge the device fully using the provided USB-C cable. |
| Cannot pair with a Bluetooth device. | Device not in pairing mode; Bluetooth device too far; interference; incompatible device. | Ensure the LE505 is in the correct TX/RX mode and pairing mode (flashing light). Place devices closer. Turn off other Bluetooth devices. Some specific Bluetooth devices (e.g., certain AirPods models) may have known compatibility issues with third-party adapters. |
| No sound or poor sound quality. | Incorrect cable connection; volume too low; incorrect audio source/output selected; low battery. | Check all 3.5mm cable connections. Adjust volume on both the LE505 and connected devices. Ensure the correct audio output is selected on your source device (e.g., TV headphone jack). Recharge the LE505. |
| Audio lag in TX mode. | Connected headphones/speakers do not support aptX Low Latency. | For optimal low latency, ensure both the LE505 and your Bluetooth headphones/speakers support aptX Low Latency. RX mode does not support low latency. |
| Dual link not working. | Second device not in pairing mode; pairing button not pressed. | Ensure both Bluetooth headphones/speakers are in pairing mode when attempting to connect. Press the 'B' pairing button after the first device is connected. |
