OH Yes yours is broken!!!
You can send them all to me.. at PO box blah blah...

No, seriously you have to hold down the 'button' for it longer than you think.
As microsoft says "THIS BEHAVIOR IS BY DESIGN"
Meaning like it or lump it...

I think it is set like that so that you don't turn it off by accident and think the speaker broke. The time set 'edit' button also id like that too.
I guess so the time doesn't get screwed_up while it's in your pocket.

PS: Big-Lots is gonna be the new wal-mart buy stock while it's cheap or somethig...
