Save and Restart System
After the settings have been saved to NV-RAM, they will become the default
settings for the device, and they will be used every time it is powered on, reset
or rebooted. The only exception to this is a factory reset, which will clear all
settings and restore the unit's settings back to their initial values, which were
present when the device was purchased.
Click on Save Configuration at the bottom of the window to save the system
settings to NV-RAM.
