- Insert the GIGASTONE SD card into the designated slot on the 3-in-1 card reader.
- Connect the card reader to your computer, smartphone, or tablet using the appropriate connector (USB Type-A, USB Type-C, or Micro USB).
- Your device should automatically detect the card reader and the SD card, allowing you to access files.

5. Operation
5.1 Recording and Storing Data
- Once the SD card is inserted into your camera or device, it will be ready for use.
- For optimal performance, especially with 4K video, ensure your device's settings are configured to utilize the high-speed capabilities of the card.

5.2 Transferring Data
- Connect the 3-in-1 card reader with the SD card inserted to your computer or compatible device.
- Open the file explorer (Windows) or Finder (macOS) and locate the removable drive corresponding to your SD card.
- Drag and drop files to and from the SD card as needed. For large files, ensure your computer's USB port supports USB 3.0 or higher for maximum transfer speeds.

5.3 Formatting the SD Card
It is recommended to format your SD card periodically, especially when using it with a new device or experiencing performance issues. Formatting erases all data on the card, so ensure you back up any important files first.
- Insert the SD card into your camera or computer.
- Access the formatting option through your device's menu or computer's disk management utility.
- Select the SD card and choose the appropriate file system (e.g., exFAT for SDXC cards).
- Confirm the format operation.
6. Maintenance
- Proper Handling: Always handle the SD card by its edges. Avoid touching the metal contacts to prevent damage or data corruption.
- Storage: Store the SD card in its protective case or a secure environment when not in use to prevent physical damage, dust, and static electricity.
- Ejection: Always safely eject the SD card from your computer or device before physically removing it to prevent data loss or corruption.
- Data Backup: Regularly back up important data from your SD card to another storage device (e.g., computer hard drive, cloud storage) to prevent permanent data loss.
- Cleaning: If necessary, gently clean the metal contacts with a soft, lint-free cloth. Avoid using liquids or abrasive materials.
7. Troubleshooting
7.1 SD Card Not Recognized
- Reinsert the Card: Remove the SD card and reinsert it firmly into the slot.
- Check Compatibility: Ensure your device supports SDXC cards and the capacity (512GB).
- Try Another Device/Reader: Test the SD card with a different camera or the included card reader to determine if the issue is with the card or the device.

- Clean Contacts: Gently clean the metal contacts on the SD card with a soft, dry cloth.
