4. Operating Instructions
Once connected, the Hicober card reader allows for bidirectional data transfer, meaning you can copy files from your device to the card, and from the card to your device.
- Transferring Files: Open your device's file management application (e.g., 'Files' on Android, 'Finder' on Mac, 'File Explorer' on Windows). Locate the external storage device (often labeled as 'USB Storage' or 'SD Card'). You can then drag and drop, copy, or move files between your device's internal storage and the memory card.
- Simultaneous Use: The card reader supports reading two memory cards (SD and Micro SD) and a USB 2.0 device simultaneously. This allows for efficient multi-tasking, such as transferring photos from an SD card while backing up files to a USB drive.
- Accessing Camera Footage: Directly view or transfer photos and videos from your digital camera, dash cam, or trail camera's memory card to your USB-C device without needing a computer.

5. Maintenance
To ensure the longevity and optimal performance of your Hicober USB C Card Reader, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to wipe the exterior of the device. Avoid using liquid cleaners or aerosols.
- Storage: Store the card reader in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting
If you encounter issues with your Hicober USB C Card Reader, please refer to the following common solutions:
- Device Not Recognized:
- Ensure the card reader is fully inserted into your device's USB-C port.
- Try inserting the memory card into the reader before plugging the reader into your device. Some devices may not recognize the storage if the card is inserted after the reader is connected.
- Test with a different USB-C port or another compatible device to rule out port issues.
- Restart your device.
- Slow Transfer Speeds:
- Ensure your memory card is capable of high-speed transfers (e.g., UHS-I or higher for optimal performance).
- Verify that your device's USB-C port supports USB 3.0 (or higher) for maximum speed. If it's a USB 2.0 port, speeds will be limited to 480 Mbps.
- Avoid running multiple demanding applications during large file transfers.
- Card Not Reading:
- Check if the memory card is inserted correctly and fully into its slot.
- Ensure the memory card is not locked (check the small switch on the side of standard SD cards).
- Test the memory card with another reader or device to confirm it is not corrupted or damaged.
