7. Benefits and How It Works
The feangli Red Light Therapy Pad utilizes specific wavelengths of light to penetrate tissues and promote various cellular responses.
7.1 Wavelengths Used
- 660nm Red Light (Visible): This wavelength penetrates into the skin's dermis layer. It is associated with improving blood circulation, aiding in muscle damage repair, and addressing certain skin concerns.
- 850nm Infrared Light (Invisible): This wavelength penetrates deeper into tissues, reaching bones, muscles, organs, and the hypodermis. It is believed to help relieve pain, accelerate wound healing, repair joint damage, promote muscle relaxation, and reduce inflammation.

7.2 Potential Benefits
- Pain relief
- Reduction of inflammation
- Faster wound healing
- Muscle and joint damage repair
- Improved blood circulation
- Muscle relaxation
- Support for skin health and collagen production

8. Maintenance
- To clean the pad, gently wipe the surface with a soft, damp cloth.
- Do not immerse the device in water or any other liquids.
- Store the therapy pad in a cool, dry place away from direct sunlight when not in use.
- Avoid folding the pad tightly or placing heavy objects on it to prevent damage to the internal components.
9. Troubleshooting
- Device not turning on: Ensure the power cable is securely connected to both the pad and the power source. Verify that the power source (e.g., power bank or wall outlet) is functioning correctly and provides at least 5V 2A.
- Lights not activating: Check the mode selection on the remote control to ensure a light mode (Red, Infrared, or Combined) is selected.
- Pad feels too hot or not warm enough: Adjust the intensity level (L0-L4) using the remote control. Note that infrared light is invisible and may not produce significant heat sensation on the surface, but it is still active.
- Remote control unresponsive: Disconnect and reconnect the power to reset the remote. If issues persist, contact customer service.
