Press the "Menu" button again if the lockout message remains on the screen.
Use the arrow buttons to navigate through the main menu options.
Highlight the "Settings" or "OSD Menu" option and then hit the Menu key again to access the new list of settings.
Scroll down to the "OSD Lock" heading. Use the arrow keys to change the setting to "No." Hit the Menu key again to return to the main menu. Scroll to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lockout.
hope this helps
