The serial number has two important pieces of information:
- The model number
- The manufacturing date or date code. These are the same thing and you can use this date to tell how old your system is.
The numbers can be small and may be hard to see. It may be helpful to use your phone and take a picture and then zoom in to see the numbers.
Depending on your unit, your label might look different. Here are a few examples and how to read them:
