5. Maintenance
- Cleaning: Use a soft, dry cloth to wipe the surface of the light box. Avoid abrasive cleaners or solvents that may damage the plexi surface.
- Storage: When not in use, store the light box in a dry, dust-free environment. Its ultra-thin profile allows for easy storage in drawers or upright against a wall.
- Handling: Handle with care to avoid dropping or impacting the device, which could damage the internal components or the surface.
6. Troubleshooting
- Light Box Not Turning On:
- Ensure the USB Type-C cable is securely connected to both the light box and a functioning power source.
- Verify that the power source (wall adapter, power bank, laptop) is providing adequate power (5V, 1-2A recommended).
- Try a different USB cable or power source to rule out a faulty component.
- Inconsistent Brightness:
- Ensure the power button is not being accidentally pressed or held, which could change the brightness setting.
- If using stepless dimming, ensure you are holding the button for the desired duration to reach the preferred brightness.
- Light Leakage: The light box features safe rounded edges to minimize light leakage. If you notice significant light leakage, ensure the device is placed on a flat surface.
