Who makes tender tykes digital pacifier thermometer with musical lullabye?

I have a tender tykes mucisal thermometer (pacifier) for my child. It is now showing temperature in celcius instead of farenheit. I have misplaced the instruction manual, and cannot find it online anywhere. I am trying to reset the thermometer rather than do the conversion each time I take my baby's temperature. I bought the thermometer at either Walgreen's or Target. Thanks for the help.
