For Vector users: In this manual, you may encounter a couple of unfamiliar terms: Midlife and Pre-
Midlife. The difference between the two is simply when the instrument was produced; pre-midlife are
instruments produced before 2009. If you are unsure about what version you have, you can check the
firmware version or send us an email with the serial number and we will check it out for you. If your
current firmware version number starts with 0.xx or 1.xx, your instrument is a so-called Pre-Midlife
version. If your current firmware version starts with 2.xx or above, it is a Midlife version.
