Reset Button
Hold the reset button down for 5 seconds to load the factory default configuration. After loading
the factory defaults, the system will reboot automatically. We recommend that you use this
function only if the software is not working properly. To reset the Linux system software, always
use the software reboot command (“reboot”) to protect the integrity of data.
The reset button is NOT designed as a hard reboot for the embedded computer.
ATTENTION
Restoring default settings preserves your data
Resetting the embedded computer to factory defaults will NOT format the user directory and will
NOT erase the user’s data. The reset button only loads a configuration file. All files in the /etc
directory will revert to their factory defaults, but all other user data will remain intact in the Flash
ROM.
Please note that if there is a problem with the /etc directory, the embedded computer may be
unable to restore the factory default settings.
