ESN is required on Erase or Print
We have this enabled by default to prevent the user from missing this key information that may result in a bad device.
How Required Field settings work
Required Fields: Here you can choose what information you want to ensure is checked on every device that is processed
Restrict Actions: Here you can choose what actions you want to restrict the tester from performing if the necessary Field information isn't collected.
i.e. If you want to ensure that all devices are given a Color or a Grade before a label is printed or erased.
