4. Operating Instructions

The SanDisk Extreme PRO SD UHS-II USB-C Reader is designed for simple plug-and-play operation:

1. Automatic Recognition: Once connected to your computer and with an SD card inserted, your operating system (e.g., Windows, macOS) should automatically detect the reader as a removable storage device.

3. Transferring Files: You can now drag and drop files or copy and paste them between your SD card and your computer. For optimal transfer speeds, especially with UHS-II cards, ensure your computer's USB-C port supports the necessary data transfer rates.

5. Maintenance

To ensure the longevity and optimal performance of your SanDisk Extreme PRO SD UHS-II USB-C Reader, follow these maintenance guidelines:

• Keep Clean: Use a soft, dry, lint-free cloth to gently wipe the exterior of the reader. Avoid using liquid cleaners or solvents.
• Protect Connectors: Keep the USB-C connector and SD card slot free from dust, dirt, and debris. You may use a can of compressed air for this purpose, holding it upright to prevent propellant discharge.
• Avoid Extreme Conditions: Do not expose the reader to extreme temperatures, direct sunlight, or high humidity.
• Safe Storage: When not in use, store the reader in a protective pouch or a clean, dry environment to prevent physical damage.

6. Troubleshooting

If you encounter issues with your SanDisk Extreme PRO SD UHS-II USB-C Reader, try the following solutions:

  • Try connecting the reader to a different USB-C port on your computer.
  • Restart your computer.
  • Check your computer's Device Manager (Windows) or System Information (macOS) to see if the device is listed.
• SD Card Not Reading:
  • Ensure the SD card is inserted correctly and fully into the reader's slot.
  • Try using a different SD card to determine if the issue is with the card or the reader.
  • Inspect the SD card for any visible damage or bent pins.
• Slow Transfer Speeds:
  • Verify that your SD card is a UHS-II card to achieve the advertised high speeds.
  • Ensure your computer's USB-C port supports USB 3.0 or higher for optimal performance. Older USB standards will result in slower speeds.
