OSD Lock / Unlock

This feature allows you to secure the current control settings, while allowing the user to adjust Brightness and Contrast, so that they cannot be inadvertently changed. You can unlock the OSD controls at any time by using the same procedure.

Push and hold the button for 10 seconds to Lock or to Unlock. When locked, a “CONTROLS LOCKED” message will be displayed.
