- Bruni Screen Protector(s)
- Microfiber Cleaning Cloth
- Mounting Card/Squeegee
- Dust Removal Sticker (if included)
- Installation Guide
2.2 Installation Steps
- Clean the Screen: Use the provided microfiber cloth to thoroughly clean the Alpine IVE-W530BT display. Ensure there are no dust particles, smudges, or fingerprints. For stubborn marks, a screen cleaning solution can be used, followed by drying with the microfiber cloth.
- Remove Dust: Use a dust removal sticker (if provided) to lift any remaining dust particles from the screen surface. This step is critical for preventing bubbles.
- Align the Protector: Carefully peel back a small portion of the protective layer (usually marked "Step 1" or similar) from one end of the screen protector. Align the exposed edge of the screen protector with the corresponding edge of your device's screen. Ensure precise alignment with all cutouts (if any) and edges.
- Apply Gradually: Slowly peel off the rest of the protective layer while simultaneously applying the screen protector to the display. Use the mounting card/squeegee to gently push out any air bubbles towards the edges as you apply. Work from one end to the other, maintaining even pressure.
- Remove Bubbles: If bubbles appear, gently lift the nearest edge of the screen protector and re-apply, using the squeegee to push the air out. Small bubbles may disappear on their own within 24-48 hours.
- Final Polish: Once applied, use the microfiber cloth to gently wipe down the screen protector, removing any smudges or fingerprints from the application process.

4. Maintenance
To ensure the longevity and clarity of your Bruni Screen Protector, follow these simple maintenance guidelines.
4.1 Cleaning
- Use a soft, lint-free microfiber cloth to gently wipe the surface of the screen protector.
- For smudges or fingerprints, lightly dampen the microfiber cloth with water or a screen-safe cleaning solution. Avoid harsh chemicals, alcohol, or abrasive materials, as these can damage the film.
- Wipe in one direction to avoid streaks.
4.2 Protection
- While the screen protector is scratch-resistant, avoid placing your device with sharp objects (e.g., keys, coins) that could potentially damage the film.
- The film offers protection against minor impacts. However, it is not indestructible and extreme force can still damage the underlying screen.

5. Troubleshooting
Here are solutions to common issues you might encounter during or after installation.
5.1 Bubbles After Installation
- Small Bubbles: Many small bubbles, especially those caused by trapped air, will naturally dissipate within 24-48 hours.
- Large Bubbles/Dust: If a bubble is large or appears to have a dust particle underneath, gently lift the nearest edge of the screen protector using a piece of tape or your fingernail. Use a dust removal sticker to carefully lift the dust particle from the screen or the protector's adhesive side. Re-apply the protector, using the squeegee to smooth it down.
5.2 Misalignment
- If the screen protector is significantly misaligned immediately after application, you can gently peel it off entirely. Ensure no dust adheres to the adhesive side during removal. Re-clean the screen and attempt re-application, paying extra attention to alignment. The glue-free nature allows for repositioning.
5.3 Edges Not Sticking
- Ensure the screen edges are perfectly clean and free of dust or oil before application.
- Apply firm, even pressure with the squeegee along the edges during installation to ensure optimal adhesion.
- If an edge lifts after some time, it might be due to a case pushing against it. Ensure your device case is compatible with screen protectors.
