Flash Corruption Errors
Also known as a factory reset, it’s a good idea to reset the flash if your card reader isn´t working the way it´s supposed to.
Resetting the flash erases the working memory of the card reader clearing out any corrupted flash. After the flash has been reset on a card reader it needs to fetch the terminal software and terminal configurations again.
Resetting the flash will not cause problems for the card reader.
Resetting the flash:
Press C and ← (back button)
Enter password: 746723 and press OK
Scroll menu using ↓ (down arrow) to Config and press OK
Select “RESET FLASH“ and press OK
Return to the previous menu by pressing C
Scroll down to “Save and Reset“ and press OK
The card reader should now restart
