You might need it to determine your appliance's warranty status, or you might need it to help you decide whether it is time to replace your appliance. Knowing the date your appliance was manufactured can be useful. The confirmed date range for the main sequence so far is given below.GE Appliance - How to Determine the Age or Manufacture Date The mismatching examples tend to be membrane keyboards. A number of mismatching examples could be found on rzwv’s site, but that has since been deleted, along with all the serial numbers. External serial numbers may use a prefix letter and still not match.
Where there is only an external serial number, this may also follow the main sequence (as with FKB4700 models), but often it does not. In these cases, the main sequence serial number is recorded on the internal label affixed to the PCB. Many Fujitsu keyboards use separate serial numbers internally and externally. The datasheet for FKB4701 Series confirms the month codes and the year range from P (2000) to Z (2010). It has been confirmed for the year range 1980–2010. The year is represented with a single character, using every letter of the alphabet, and wrapping around from Z back to A in 1985. The positions have the following interpretations: y Year of production (A–Z) see under examples below m Month of production (0–9, X–Z) see table below sssss Running digits (four up to around 1984, and five from around 1985 onwards external serial numbers can have six running digits) t A suffix letter, not explained often “t”, but “e” has also been seen
The “main sequence” format appears is as follows: Jump to page content Main site navigation:įujitsu used multiple serial number formats.
