3. Setup
- Inserting the Micro SD Card: Locate the Micro SD card slot on your device. Gently insert the Micro SD card with the gold contacts facing down (or as indicated by your device's manual) until it clicks into place.

- Initial Device Recognition: Upon first insertion, your device may prompt you to format the card. Follow the on-screen instructions. Formatting will erase all data on the card, so ensure it is new or backed up if it contains data.
- Formatting (if necessary): If your device does not automatically prompt for formatting, navigate to your device's storage settings and select the option to format the Micro SD card. This prepares the card for optimal use with your specific device.

- Proper Handling: Avoid touching the gold contacts on the card to prevent damage or corrosion. Always store the card in its protective case when not in use.

Card Not Recognized by Device:
