NOTE
Menu preferences are not normally retained after the
power is removed from the instrument. To make (a)
menu preference(s) permanent, make the desired
change(s) to settings first and then proceed to the
section Storing the Menu Preferences to make the
changes permanent. Following this procedure will put
the settings into non-volatile memory and allow them
to be restored during instrument power-up.
