To add an additional manufacturer to the NT520 Pro, we need you to confirm your tool's serial number.
This is especially important if you didn't originally purchase your tool from us, as we will not have a record of it.
The serial number can be found on a label on the back of the tool, and begins with "N5B" - it will be in the format N5B0801234567
It can also be found by clicking
Setup, then selecting
About.
