Convert the service ID to an actual date
You can use the product Service ID number to determine whether the product is still under warranty.
Use the following formula to convert the Service ID into the installation date as follows:
1. Add 1990 to YY to get the actual year that the product was installed.
2. Divide DDD by 30. If there is a remainder, add 1 to the result. This is the month.
3. The remainder from the calculation in step 2 is the date.
Using the Service ID 12287 as an example, the date conversion is as follows:
1. 12 + 1990 = 2002, so the year is 2002.
2. 287 divided by 30 = 9 with a remainder of 17. Because there is a remainder, add 1 to 9 to get
10, which represents October.
3. The remainder in step 2 is 17, so that is the date.
4. The complete date is 17-October-2002.
NOTE: A six-day grace period is built into the date system.
