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 the 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 shared folders
previously created will be cleared. To retrieve the old data after advanced
system reset, create the same shared folders on the NAS and the data will be
accessible again.
