Reset Button
Press the Reset button on the front panel continuously for at least 5 seconds to load the factory default
configuration. After the factory default configuration has been loaded, the system will reboot automatically.
The Ready LED will blink on and off for the first 5 seconds, and then maintain a steady glow once the system
has rebooted.
We recommend that you only use this function if the software is not working properly and you want to load
factory default settings. To reset an embedded Linux system, always use the software reboot command
/>reboot to protect the integrity of data being transmitted or processed. The Reset button is not designed to
hard reboot the DA-660/662.
ATTENTION
Pressing the Reset button will only load the configuration file. All files in the /etc directory will revert to their
factory defaults, and all user data in the Flash ROM will be deleted.
