The following information was obtained directly from Motorola and sent to Repeater-Builder for inclusion in this document.
Motorola Solutions equipment serial numbers follow two standard formats.
First format: three digits, three letters, and four digits: The fifth character of the serial number represents the YEAR code and the sixth character represents the MONTH code. Example:
2 0 3 F L W 6 4 2 1
Decodes to 2010 (L), first half of November (W).
Second format: two digits, four letters, one digit, and four letters: The ninth character of the serial number represents the YEAR code, the tenth character represents the MONTH code and the eleventh character represents the WARRANTY period code. Example:
5 2 C B A C 8 D L W J
Decodes to 2010 (L), first half of November (W), 1 Year Standard Warranty (J).
The values in each position correspond to the following pre-determined year, month or warranty period codes. Note that there are two entries for every month: the first represents the first half of the month; the second represents the second half of the month.
