Ramp-Up Transition from
Stimulation to Expression Phase.
When switching from Stimulation
to Expression Phase, the
Symphony 2.0 Program Card
increases the vacuum setting
by adding 3 bars to the last
Stimulation setting in a stair-
stepped fashion. The 3 additional bars and increased
vacuum setting occur gradually over a 4-second period.
The ramp-up transition eliminates potential discomfort of
an immediate vacuum setting increase.

the let-down button can also be used to switch back to
Stimulation Phase. For more information on this feature,

ejection occurs before the 2 minute Stimulation Phase is over, press
the let-down button and continue pumping in Expression Phase
