Instrument Preset enables you to set the Signal Genera-
tor to an initialized state. Partial Preset (f^l (S] )
is a quick way to set the Signal Generator to another
initialized state without affecting some instrument
settings; for example, Partial Preset does not turn off
the EMF or Amplitude Relative mode.
Holding the Shift key down during power-up until
instrument settings are displayed bypasses the power-up
checks.
