Creating a reset-to-factory-defaults memory card
You can create a memory card that will return the CPU to a factory default state. You can
use this reset-to-factory-defaults memory card if you ever want to clear the contents of your
CPU. To create a reset-to-factory-defaults memory card, follow these steps:
1. Using a card reader and Windows explorer, delete all contents from a microSDHC card.
2. Create a simple text file with an editor such as Notepad that contains one line with the
string "RESET_TO_FACTORY". (Do not enter the quotation marks.)
3. Save this file to the microSDHC card root level under the file name "S7_JOB.S7S".
4. Label the card and store it in a safe place for future use.
