2.2 Removing the Memory Card

Before removing the card, ensure that your device is powered off or that no data transfer operations are in progress to prevent data loss or corruption.

1. Gently press the card inward until you hear a click.
2. Release the card, and it will partially eject from the slot.
3. Carefully pull the card out of the slot.

2.3 Write Protection Switch

The Lexar Professional 633x SDXC card features a small write-protection switch on its left side. This switch controls the card's read/write capabilities:

• Locked Position (Switch Down): When the switch is in the down position, the card is write-protected. This prevents new data from being written to the card and existing data from being deleted or modified.
• Unlocked Position (Switch Up): When the switch is in the up position, the card allows full read and write access.

Always ensure the switch is in the unlocked position when you intend to save new files or delete existing ones. If you encounter an error message indicating the card is write-protected, check the position of this switch.

4. Maintenance and Care

4.1 Formatting the Card

It is recommended to format your memory card periodically to maintain optimal performance and ensure compatibility, especially when using it with a new device or after significant data transfer. Always back up all data from the card before formatting, as formatting will erase all content.

• Select the Lexar SDXC card and initiate the format process.

To ensure the longevity and reliability of your memory card:

• Avoid exposing the card to extreme temperatures, high humidity, or direct sunlight.
• Do not bend, drop, or apply excessive force to the card.
• Keep the metal contacts clean and free from dust, dirt, or debris.
• Store the card in a protective case when not in use to prevent physical damage.

5. Troubleshooting

If you encounter issues with your Lexar Professional 633x SDXC card, consider the following troubleshooting steps:

5.1 Card Not Recognized or Data Transfer Issues

• Verify the Write Protection Switch: Ensure the small write-protection switch on the side of the card is in the unlocked (up) position.
• Test with Another Device: Try the card in a different camera, camcorder, or card reader to determine if the issue is with the card itself or the device you are using.
• Test with Another Port: If using a computer, try a different USB port or card reader slot.
• Check Computer Settings: If you are using a company computer, confirm that IT policies do not block saving files to removable drives.
• Reformat the Card: If possible, back up your data to another storage device, then reformat the card using your device or computer.
• Clean Contacts: Gently clean the metal contacts on the card with a soft, dry, lint-free cloth.

5.2 Slow Performance

• Device Compatibility: Ensure your device fully supports UHS-I and the specified speed classes (U3, V30) for optimal performance. Older devices may not be able to fully utilize the card's speed capabilities.
• Card Reader: For faster data transfer to your computer, use a high-speed card reader (e.g., USB 3.0 compatible).
• Fragmentation: Periodically backing up all data and then reformatting the card can help maintain optimal write and read performance.

If these steps do not resolve your issue, please contact Lexar customer support for further assistance.
