The first two characters of the date-of-manufacture code give the last two digits of the year (for
example, “06” appears for products manufactured in 2006). The last character of the
date-of-manufacture code gives the month in which the product was manufactured. The month
appears in the form of a single alphanumeric character: “A” for January, “B” for February, “C”
for March, and so on through “L” for December.
The product serial number is a unique set of alphanumeric characters that ZOLL assigns to each
individual unit.
