Stop/Exit keys simultaneously (for models without numerical keypad).

If the displayed version number is identical with the firmware version you installed, the
loading operation has been successfully finished.
Note: If loading operation ends abnormally, turn the machine off and on. Wait for the machine
to emit a long beep and automatically enter the firmware loading mode, and then perform the
loading procedure above again.
