EXFO MaxTester 635G User Manual page 105

If Manual is selected, the FED Type is set to TS125
by default. When FED is Manual, you can set the
FED to a desired state independently from the one
defined currently in the FED setup for a particular
test. This state will be kept indefinitely until you
set the FED to another one, change the mode to
Auto, or disable the FED. The Manual state of the
FED Control is not saved in the profile and is only
kept for the time of the current session. If you
leave the copper application, at next startup FED
will be set to the value saved in the profile:
Disabled or Auto.
