Dritz Mighty Steam Iron with dual voltage
 

Does anyone have one of these? I got one for Christmas and can't wait to try it! The instructions say "Make sure the dual voltage selector is in the correct position before operating," but doesn't say how to make sure it's in the correct position. I'm in the US so I'm assuming it needs to be set at 110-122v rather than220-240v, but beyond that I'm not sure how to make sure it's in the correct position. Can anyone help?

Should be a tab or slider on the bottom or rear, one side will say 110, other side will say 220. Slide the tab over to 110.
