Locking the menu
Allows you to control user access to settings. When Lock is selected, none of the users have setup privileges. All buttons are locked.
ATTENTION:
When the OSD menu is locked, pressing the menu button redirects the user directly to the OSD setting menu with the OSD Lock option selected. Select "Unlock" to unlock and allow users to access all settings.
