Appendix C: Factory defaults
When your TVS leaves the factory, it comes with default settings and configuration. Configuring and
programming your TVS changes the factory defaults. Resetting your TVS erases all the configuration
and settings you programmed and then restores the defaults. For more information, read Restoring
the factory defaults
on page 43.
The following table lists all the factory defaults and ranges.
