* Some parameters in the Profile Status Menu can be changed for the
currently running profile, but should only be changed by knowledgeable
personnel and with caution. Changing parameters via the Profile Status
Menu will not change the stored profile but will have an immediate im-
pact on the profile that is running.
Changes made to profile parameters in the Profiling Pages will be
saved and will also have an immediate impact on the running profile.
