whats the difference between CBOK and CSSN series that i got? or is it CSSK? print is faded
C = 12, or 2012
B = 11, or Nov
So CB0K means it was manufactured in Nov '12. CSSK doesn't seem like a valid hexadecimal value, so you might want to double check. The label on your box should have a section labeled "SSN" that will determine when your device was made.
