the backup file and on the
TEC device.

for the TEC that is showing the
issue.
2. Edit the backup file created in the
previous step on a PC to reflect the
desired settings.
3. Verify that the modified values are
within minimum and maximum
range in the backup file.
4. Restore the settings from the newly
edited backup file on the TEC.
