Note: If the user has saved a profile (curve) to memory and decides to stop the
Adaptive Pre-correction process, the user should navigate to the Non-linear and/or
Linear Pre-corrector pages and select the desired profile from the pull-down menu and
ensure that the state is set to β€œON”. This will ensure that Non-linear and/or Linear Pre-
correction is enabled following a modulator reset and that the correct profile (curve) is
loaded.
