Vaxson Privacy Screen Protector User Manual

1. Introduction

This manual provides instructions for the Vaxson Privacy Screen Protector, designed for the GOKOO/NACATIN SN80 1.3" smartwatch. This protective film is made of flexible plastic and is intentionally sized slightly smaller than the display to accommodate the curved edges of the smartwatch screen. It offers privacy, scratch resistance, and maintains touch sensitivity.

2. Key Features

• Privacy Protection: The screen content is visible only to individuals directly in front of the display. From side angles (approximately 45 degrees or more), the screen appears dark, protecting your sensitive information from onlookers.

• 4H Hardness: Provides protection against daily scratches, scrapes, and normal wear. It resists scratches up to 4H hardness, helping to maintain the screen's integrity.

• Self-Healing Technology: Minor scratches on the film can recover within 48 hours, helping to keep your screen looking new.
• High Sensitivity: The ultra-thin material ensures that the screen remains fully responsive to every touch and tap, providing a smooth user experience for applications, games, and video playback.

3. Setup & Installation

Follow these steps for a smooth and bubble-free installation of your Vaxson Privacy Screen Protector:

1. Clean the Screen: Thoroughly clean your smartwatch screen using the provided cleaning kit (if included) or a microfiber cloth to remove all dust, smudges, and fingerprints. Ensure the screen is completely dry.
2. Align the Protector: Carefully peel off the protective layer from the adhesive side of the screen protector. Align the protector precisely with the edges and cutouts of your smartwatch screen.
3. Apply the Protector: Once aligned, gently place the screen protector onto the smartwatch screen. The design allows for a 'one-push' easy installation.

4. Remove Bubbles: If any small bubbles appear, gently push them towards the edges of the screen using a soft cloth or a squeegee card (if provided). Most small bubbles will disappear within 24-48 hours due to the self-healing properties.

Note: The screen protector is intentionally made smaller than the display due to the curved edge of the smartwatch display. This is normal and ensures proper adhesion without lifting.

4. Operation (Privacy Function)

The Vaxson Privacy Screen Protector functions by limiting the viewing angle of your smartwatch display. When viewed directly from the front (90-degree angle), the screen is clear and fully visible. However, when viewed from an angle of approximately 45 degrees or more from either side, the screen darkens significantly, making the content unreadable to others.

To optimize the privacy effect, you may need to adjust your device's display brightness. The privacy feature inherently darkens the screen slightly, so increasing brightness can improve your personal viewing experience without compromising privacy for others.

5. Maintenance

• Cleaning: To clean the screen protector, gently wipe it with a soft, lint-free cloth. For stubborn smudges, slightly dampen the cloth with water or a screen cleaner specifically designed for electronics. Avoid harsh chemicals.
• Scratch Recovery: The self-healing technology allows minor scratches to disappear within 48 hours. Avoid intentionally scratching the protector with sharp objects.
• Removal: If you need to remove the screen protector, gently peel it off from one corner. It is designed to leave no sticky residue.

6. Troubleshooting

• Bubbles After Installation: Small bubbles are common immediately after installation. Most will dissipate naturally within 24-48 hours due to the self-healing material. For larger bubbles, try gently pushing them to the edge with a soft cloth.
• Reduced Screen Brightness: The privacy feature inherently darkens the screen. If you find the screen too dim for your preference, increase your smartwatch's display brightness setting.
• Touch Sensitivity Issues: If you experience reduced touch sensitivity, ensure the screen protector is applied correctly without any lifting edges or trapped debris. The material is designed to maintain high sensitivity.
• Protector Not Sticking: Ensure the screen was thoroughly cleaned and dry before application. If edges are lifting, gently press them down. If the issue persists, the protector may need to be replaced.
