I own a sansa fuze display model but I think it's stuck in demo mode?

My friend gave me a 2gb sansa fuze they received from working at a best buy store.  They got it for free because it was the old display model.  

I’ve realized that there is no “settings” option.  The only options on the menu are: Music, Voice, FM Radio, Photos, Videos, and slotRadio.

I would really like to find out a way to access the settings menu.  Is there any way to reset this to factory settings without accessing the settings menu?  Does anyone know how to get the fuze out of demo mode or access the settings menu?

Try Pushing the power switch up and holding it there for like 30 seconds see if that helps.
