Not all items on the label are always used. Please note that the label differs from the product photograph. Here is the layout of the label: The manufacturing date code is four characters: First character Last digit of manufacturing year, example 2009 Second character Month code (1 through 9 = Jan-Sep XXXXXX Product code Mfg. O, N, D = Oct, Nov, Dec) date YMDX Rev. Revision level code Third character Day code (1 through 9 = 1 to 9, 10 = 0 and 11 through 31 = A through Z) Figure 2.
