1. Ensure your Koobee K100 phone is clean and free of dust or debris.
2. Align the phone with the case, starting with the top or bottom edge.
3. Gently press the phone into the case, ensuring all corners and edges are securely fitted.
4. Verify that all ports, buttons, and camera cutouts align correctly with the phone.

3.2 Applying the Tempered Glass Screen Protector:

1. Clean the Screen: Use the provided cleaning wipes (if any) or a microfiber cloth to thoroughly clean your phone's screen. Ensure no dust, smudges, or fingerprints remain.
2. Remove Dust: Use a dust-absorber sticker (if provided) to remove any remaining dust particles from the screen.
3. Peel Off Protective Film: Carefully peel off the protective film from the adhesive side of the tempered glass screen protector. Avoid touching the adhesive surface.
4. Align and Apply: Carefully align the screen protector with your phone's screen, paying attention to the cutouts for the speaker, camera, and home button. Once aligned, gently lower the protector onto the screen.
5. Press and Smooth: Lightly press the center of the screen protector. The adhesive will spread outwards. Use a clean cloth or your finger to gently push out any air bubbles towards the edges.

5. Maintenance and Care

• Ring Support Care: Ensure the ring mechanism remains free of dirt or debris to maintain smooth rotation. If the adhesive weakens over time, it may be necessary to replace the ring support.
