* Note: For the models above, excluding the AVR340, the full On Screen Display (OSD) normally will not be visible with Component
video connections alone. For model AVR340, when the component video jacks are used, the onscreen menus are not visible with
high-definition video (720p or 1080i), and you must switch to the standard composite or S-video input on your TV, or to a 480p video
source, to view them.
