How to use

Insert the Lexar SDXC card into a compatible SD card slot in your camera, camcorder or card reader with the label side facing up until it clicks into place. Format the card in the device before first use to ensure optimal file system settings and compatibility. During recording, monitor available space and remaining battery to avoid corrupt files; when transferring files, use a UHS-I compatible card reader and ensure the computer’s USB connection is stable. Eject the card safely from the operating system after file transfer to prevent data loss.

Usage recommendations

For reliable 4K video and continuous burst shooting, format the card in-camera and avoid full-capacity operation for extended periods; keep a second card as backup. Store the card in a protective case when not in use and avoid removing the card while the device is writing data.
