Setup and Installation
Proper installation is crucial for optimal performance. Please follow these steps carefully:
1. Prepare Your Workspace
Choose a clean, dust-free environment with good lighting. Wash your hands thoroughly to avoid transferring oils or dirt to the screen or protector.
2. Clean the Device Screen
Turn off your Pax A8900 K4 device. Use the provided wet pad to thoroughly clean the screen surface, removing any smudges, fingerprints, or dirt. Follow with the cleaning wipe to dry the screen completely. Ensure no lint or dust particles remain.

3. Remove Dust with Dust Remover
Use the dust remover sticker to gently dab the screen surface. This will pick up any remaining dust particles that might cause bubbles under the protector.
4. Align the Screen Protector
Carefully peel back a small portion of the protective film (labeled "1" or similar) from one end of the screen protector. Align the exposed edge of the protector with the corresponding edge of your device screen. Use the guide stickers if necessary to hold the protector in place for precise alignment.
5. Apply the Screen Protector
Once aligned, slowly and steadily peel off the rest of the protective film (1) while simultaneously using the smoothing card to press the screen protector onto the device screen. Work from the aligned edge towards the opposite end, applying even pressure to prevent air bubbles.
6. Remove Air Bubbles
If any small air bubbles remain, use the smoothing card to gently push them towards the nearest edge of the screen protector. For stubborn bubbles, you may carefully lift a corner of the protector slightly and re-apply while smoothing.
7. Remove Top Protective Film
Once the screen protector is fully adhered and free of bubbles, carefully peel off the top protective film (labeled "2" or similar) from the surface of the newly applied screen protector.

Maintenance and Care
To ensure the longevity and effectiveness of your screen protector, follow these simple maintenance guidelines:

- Avoid Sharp Objects: While the protector offers scratch resistance, avoid direct contact with sharp objects like keys or knives to prevent damage.
- Temperature: Avoid exposing your device and screen protector to extreme temperatures, which can affect adhesive properties.
Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bubbles under the protector | Dust particles or uneven application. | Gently lift the nearest edge of the protector and use the smoothing card to push the bubble towards the edge while re-applying. Ensure the screen is dust-free before re-application. |
| Protector not adhering properly | Oils, dirt, or dust on the screen; improper alignment. | Ensure the screen is perfectly clean and dry before application. Re-align carefully. If the issue persists, the protector may be damaged and require replacement. |
| Reduced touch sensitivity | Improper installation or a faulty protector. | Ensure the protector is fully adhered without air gaps. If the problem persists, contact customer support. |
| Scratches on the protector | Normal wear and tear or contact with sharp objects. | The protector is designed to absorb scratches to protect your device screen. If scratches become too prominent or affect visibility, consider replacing the protector. |
