Product Label Because of the small size of these products, the product label contains a Model Number Product Code character-reduced code to indicate the model number and manufacturing date OKI-T/36W-W40P-C IW1136 code. Not all items on the label are always used. Please note that the label dif- OKI-T/36W-W40N-C IW0136 fers 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 and O through D) code Third character Day code (1 through 9 = 1 to 9, 10 = O and 11 through 31 = A through Z) Figure 2.
