Connecting games console to Packard Bell onetwo L8500

Obsidian Rocker

So, to keep things short, I have my xbox 360 connected to this Packard Bell oneTwo L5800 via HDMI cable. Problem is, I dunno how to change the 'channel' so I can see the xbox and play it. Apparently there's supposed to be a button on the side for it, but the only ones I can see are ones for lights at the bottom and disc eject. Anyone know what I'm missing?
