8. Troubleshooting
If you encounter issues with your Eventek Heated Socks, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Socks not heating or uneven heating. | Battery not charged, loose connection, faulty battery/sock. | Ensure batteries are fully charged. Check that the battery cable is securely connected to the sock. Try swapping batteries between socks to identify if the issue is with a specific battery or sock. |
| Batteries not turning on or holding a charge. | Battery fully discharged, charging cable issue, battery defect. | Ensure the USB charging cable is properly connected and functional. Try a different USB power source. If the battery still doesn't charge or turn on, it may be defective. |
| Socks feel too hot or not warm enough. | Incorrect heat setting. | Adjust the heat setting by short pressing the power button on the battery to cycle through High, Medium, and Low. |
| Discomfort or irritation while wearing. | Heat setting too high, improper fit, skin sensitivity. | Reduce the heat setting. Ensure socks are worn correctly and not too tight. If irritation persists, discontinue use. |
