Loading Factory Defaults
To load the factory default settings, you must press the reset-to-default button for more than 5
seconds. All files in the /home & /etc directories will be deleted. Note that while pressing the
reset-to-default button, the Ready LED will blink three times, and then turn off. It takes about one
minute for the factory defaults to fully load. For users who have logged onto the computer, please
note that they will be forcibly logged out when the factory defaults are loaded and the systems
start to reboot.
