3. Installation Guide
Follow these steps to replace your smartwatch band:
- Prepare Your Smartwatch: Ensure your EIGIIS KE3 S100 Smartwatch is powered off to prevent accidental damage during installation.
- Remove the Old Band: Locate the quick-release pins or spring bars on the underside of your current watch band where it connects to the watch lugs. Gently slide the pin inwards or use a spring bar tool to release one side of the band, then carefully remove it from the watch. Repeat for the other side.
- Attach the New Band: Take one half of the yiqungo replacement band. Insert one end of the quick-release pin (or spring bar) into the corresponding hole on one side of the watch lug.
- Secure the Band: While holding the first end in place, gently push the quick-release pin inwards (or compress the spring bar) and align the other end with the opposite hole on the watch lug. Release the pin/bar, ensuring it clicks securely into place. Give a gentle tug to confirm it is properly seated.
- Repeat for the Second Half: Follow the same procedure for the other half of the yiqungo replacement band.

4. Operating and Adjustment
Once installed, the yiqungo watch band is ready for use. To adjust the fit:
- Fastening: Wrap the band around your wrist and insert the metal buckle's pin through one of the adjustment holes that provides a comfortable, secure fit without being too tight or too loose.
- Securing the Strap: Thread the excess strap through the two silicone loops to keep it neatly in place.
The silicone material offers flexibility, making it suitable for various activities, including sports and daily wear.
5. Care and Maintenance
To ensure the longevity and appearance of your yiqungo watch band, follow these maintenance guidelines:
- Cleaning: Wipe the band regularly with a soft, damp cloth to remove dirt, sweat, and oils. For deeper cleaning, use mild soap and water, then rinse thoroughly and dry completely before reattaching to your smartwatch.
- Avoid Harsh Chemicals: Do not expose the band to strong chemicals, solvents, or abrasive cleaners, as these can damage the silicone material and metal buckle.
- Storage: When not in use, store the band in a cool, dry place away from direct sunlight to prevent material degradation.
- Avoid Extreme Temperatures: Prolonged exposure to extremely high or low temperatures can affect the material's integrity.

6. Troubleshooting
If you encounter any issues with your watch band, consider the following:
- Band Not Attaching Securely:
- Ensure the quick-release pins (or spring bars) are fully retracted and properly aligned with the watch lug holes.
- Verify that the band is oriented correctly (some bands have a specific top/bottom side).
- Discomfort or Skin Irritation:
- Ensure the band is not too tight. Adjust to a looser setting.
- Clean the band regularly to remove sweat, dirt, or residue that may cause irritation.
- If irritation persists, discontinue use and consult a healthcare professional.
- Buckle Issues:
- Check for any debris or foreign objects obstructing the buckle mechanism.
- Ensure the buckle pin is straight and not bent.
