Button Lockouts

When the Primary OSD or button labels are not displayed, holding specific buttons down for ten seconds will lock out different parts of the OSD’s functionality. You can restore the functionality by holding the specific buttons down again for ten seconds. This functionality is only available when the display is powered and is displaying an active signal.

The following table lists the available lockouts and the buttons that must be held down for ten seconds to enable and disable the lockout.
