Operating Instructions
1. Capturing Photos and Videos
Once the SD card is correctly inserted into your camera, it will be ready to store photos and videos. Ensure your camera settings are configured to save media to the SD card. The SanDisk Ultra card's Class 10 and UHS-I speed rating supports Full HD video recording and rapid-fire photo capture.
2. Transferring Data to a Computer
- With the SD card inserted into the card reader and connected to your computer, open 'My Computer' or 'This PC' (Windows) or 'Finder' (Mac).
- Locate the removable drive corresponding to your memory card.
- Open the drive to access your photos and videos. You can drag and drop files to your computer's hard drive or use copy/paste functions.
- After transferring, safely eject the removable drive from your operating system before physically disconnecting the card reader.
3. Formatting the SD Card
Warning: Formatting an SD card will erase all data on it. Back up any important files before proceeding.
- It is recommended to format the SD card directly within the device (camera) you intend to use it with. Refer to your device's manual for specific formatting instructions.
- Alternatively, you can format the card via your computer's disk management tools. Right-click on the removable drive, select 'Format', and choose the appropriate file system (e.g., exFAT for 128GB cards).
