Installation Guide
Follow these steps carefully for optimal application. For a visual guide, please refer to the installation video below.
- Clean the Screen: Use the provided alcohol wipes (Wet 1 then Dry 2) to thoroughly clean your MP3 player's screen. Ensure no dust, smudges, or fingerprints remain. Finish by wiping with the microfiber cloth.
- Prepare the Protector: The screen protector has three layers. Carefully peel off the Red "Back 1" layer. This exposes the adhesive side of the middle layer.
- Apply the Protector: Align the screen protector precisely with your MP3 player's screen. Gently lay it down, starting from one edge and slowly moving across to minimize air bubbles.
- Smooth Out Bubbles: Use the squeegee to push any remaining air bubbles towards the edges of the screen.
- Remove Top Layer: Finally, peel off the Black "Front 2" layer. The middle layer is the actual screen protector that remains on your device.

Maintenance
To keep your screen protector clean and clear, regularly wipe it with a soft, lint-free cloth. The oleophobic coating helps repel fingerprints and oils, making cleaning easier.

Troubleshooting
- Bubbles After Installation: Small bubbles may disappear naturally within 24-48 hours due to the self-healing properties of the TPU material. For larger bubbles, gently lift the nearest edge of the protector and reapply, using the squeegee to push out the air.
- Protector Not Sticking Properly: Ensure the screen was thoroughly cleaned before application. If the middle layer (the actual protector) seems to lack stickiness, it's possible the "Front 2" layer was peeled off first. In this case, gently wrinkle the Red "Back 1" layer to separate it from the middle layer, then re-align the middle layer to the "Front 2" side and reapply.
- Minor Scratches: The self-healing technology is designed to constantly eliminate minor scratches and scuffs within 24 hours.
