Advanced system reset (10 sec)
Press the reset button for 10 seconds; you will hear two beeps at the third and the tenth
seconds. The NAS will reset all the system settings to default as it does by web-based
system reset in “Administration” > “Restore to Factory Default” except all the data are
reserved. The settings such as the users, user groups, and the network share folders
previously created will be cleared. To retrieve the old data after the advanced system reset,
create the same network share folders on the NAS and the data will be accessible again.
