Selecting an option from the “Configure” menu usually brings up to a series of related screens, which the administrative user navigates through one at a time until the final screen is reached.For example, if Date/Time is selected, a series of “Date/time Config.” screens appears starting with “NTP” and ending with “Time,” as shown in the following figure.As illustrated, all configuration screens except the final one have a right arrow at the bottom right that an administrative user can click to go to the next screen. Clicking “Save” on any of the screens saves any changes made to that point. An administrative user can also wait for the final screen in a series before saving changes. Clicking “Save” on the final screen saves any change and returns to the Configuration menu.Note: The Save button on every screen saves configuration changes into the configuration files. To permanently back up all configuration changes so they can be restored after an upgrade, you must also select “Save/Load Conf.” from the Configuration Menu. See How Configuration Files Changes Are Managed for more details.See Navigating the OSD, if needed, for how to use the Tab key and other keys to move around the screens in the OSD.
