Turn the TV on and select the TV video input that connects to the Lifestyle® system
on the remote, press more
press the right arrow to highlight the "options" icon, and then press ok
press the up arrow or down arrow to highlight "center speaker"
press the left arrow or right arrow to adjust the volume level of the center speaker from –8 to +8
press exit to leave the menu
