F8 LOUT
LOUT (Log out) logs you out of OSD control of the computers, and blanks the
Console screen. After using this function you must log in all over again to
regain access to the OSD.
This is different from simply pressing [Esc] when you are at the Main Screen
to deactivate the OSD, where all you have to do to reenter the OSD is tap the
OSD Hotkey.
Note: 1. When you reenter the OSD after logging out, the screen stays blank
except for the OSD Main Screen. You must input your password
before you can continue.
2. If you reenter the OSD after logging out, and immediately use [Esc]
to deactivate the OSD without having selected a port from the OSD
menu, a Null Port message displays on the screen. The OSD Hotkey
will bring up the Main OSD Screen.
