1. With your sign turned on, plug an empty USB drive into the external USB port on the sign (if equipped).
2. Leave the drive in the sign until you see a message on the sign indicating that it is ready to be removed. This will download all of your sign’s diagnostic information to the drive into a text file named signinfo.txt.
3. Plug the USB drive into your computer and open the signinfo.txt file on the drive by double-clicking on it.
