Not all items on the label are always used. Please note that the label differs OKR-T/6-W12E-C R01106E from the product photograph on page 1. Here is the layout of the label: The manufacturing date code is four characters: XXXXXX Product code First character Last digit of manufacturing year, example 2009 Mfg. date YMDX Rev. Revision level Second character Month code (1 through 9 = Jan-Sep code O, N, D = Oct, Nov, Dec) Third character Day code (1 through 9 = 1 to 9, 10 = 0 and Figure 2.
