Then, plug the other end of the USB cable into a free USB port on your TV/set-top box or into a separate USB power adapter (not included) connected to a wall outlet.

4. Operating Instructions
Once the antenna is connected and powered, follow these steps to receive digital TV channels:
- Power On: Ensure your television or set-top box is powered on. The antenna's indicator light should be illuminated, indicating it is receiving power.
- Channel Scan: Access the menu on your television or set-top box and navigate to the 'Channel Search' or 'Auto Tune' section. Select 'Antenna' or 'Air' as the signal source and initiate an automatic channel scan. The antenna's automatic adjustment amplifier will optimize the signal during this process.
- Optimize Reception: If you experience poor signal quality or missing channels, try repositioning the antenna slightly and performing another channel scan. Small adjustments can significantly impact reception quality.
5. Maintenance
To ensure the longevity and optimal performance of your antenna:
- Cleaning: Wipe the antenna with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Environment: Keep the antenna away from excessive moisture, dust, and extreme temperatures.
- Cable Care: Avoid bending or kinking the coaxial and USB cables excessively to prevent damage.
6. Troubleshooting
If you encounter issues with your antenna, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No signal or poor reception | Incorrect antenna placement, weak signal, loose connections. | Reposition the antenna, ensuring it is near a window and away from obstructions. Check all cable connections. Perform a new channel scan on your TV/set-top box. |
| Antenna indicator light is off | No power supply. | Ensure the USB cable is securely connected to both the antenna and a powered USB port (on TV/STB or a wall adapter). Try a different USB port or power adapter. |
| Missing channels after scan | Antenna not optimally positioned for all available channels. | Adjust the antenna's position slightly and perform another channel scan. Sometimes, a small change in orientation can improve reception for specific channels. |
