Introduction
This manual provides instructions for the YoLin Protective Case designed for the Apple Watch Series 3, 42mm model. This full-coverage case is engineered to protect your device from dust, fingerprints, scratches, drops, and impacts. It is made from high-quality, scratch-resistant Thermoplastic Polyurethane (TPU) and features precise cutouts for full functionality.
The package includes two cases: one rose-pink and one transparent.


Setup and Installation
Follow these steps to correctly install the protective case on your Apple Watch Series 3 (42mm) and ensure optimal screen sensitivity.
- Step 1: Clean the Watch. Use a wet cloth to clean the watch screen and its body, then dry thoroughly with a dry cloth. This prevents dust or moisture from being trapped under the case.
- Step 2: Position the Case. First, insert the side of the watch with the Digital Crown into the case.
- Step 3: Secure Corners. Gently push one corner of the watch into the case, then proceed to the remaining corners until the watch is fully seated.
- Step 4: Adjust for Alignment. This step is crucial for maintaining screen sensitivity. Adjust the position of the case to ensure that the hole in the case is perfectly aligned with the microphone and speaker of the watch. This ensures full contact between the case and the screen, preventing degradation of touch sensitivity.

Operation and Usage
The YoLin protective case is designed for daily use, providing protection while maintaining full access to your Apple Watch's features.
- Full Functionality: The precise cutouts ensure that all buttons, the Digital Crown, microphone, and speaker remain fully accessible and functional.
- Touch Sensitivity: When installed correctly, the case does not impede the touch sensitivity of the Apple Watch screen.
- Protection: The case offers comprehensive protection against scratches, minor impacts, and dust for the front face and curved edges of your Apple Watch.


Maintenance
To ensure the longevity and effectiveness of your YoLin protective case, follow these maintenance guidelines:
- Cleaning: Regularly remove the case and clean both the watch and the inside of the case with a soft, damp cloth, then dry thoroughly. This prevents accumulation of dust and debris that could scratch the watch or affect touch sensitivity.
- Moisture Management: The case is designed to protect against splashes, but moisture can become trapped between the case and the screen during activities like hand washing or intense workouts due to sweat. This can affect screen responsiveness.
How to Remove Trapped Moisture:
- Step 1: Remove Case. Take off the watch bands, then carefully remove the protective case from the Apple Watch.
- Step 2: Clean and Dry. Clean both the watch screen and the inside of the case with a wet cloth, then dry them completely with a dry cloth.
- Step 3: Reinstall. Reinstall the case by following the installation steps outlined in the "Setup and Installation" section. Ensure the case is properly aligned with the microphone and speaker.

- Solution: Remove the case and clean both the watch and the case with a soft, damp cloth, then dry completely before reinstallation.
