How do I enable the Key Lock feature to prevent unauthorised use?
Press MENU, select OPTION, select Key Lock, then select On and save. When Key Lock is On, the display 'Key Lock On' appears on screen if any front panel button is pressed during TV viewing. The TV remembers this setting even when turned off. (Page 67)
