Controls and Features
The pump has two knobs, which control its operation. Rotating the
knobs adjusts the settings. The knobs increase/decrease a displayed
value. If you continue to rotate the knobs, the values will continue to
change until the value reaches its limit. For knob locations, see the
illustration on page 11.
Cycle speed/power knob
Pressing the cycle speed/power knob starts and stops the pump
motor. Rotating the cycle speed/power knob controls the suction
rhythm (cycle). It does this by changing the speed of the pump motor
to pump faster or slower. Rotating the cycle speed/power knob
to the right increases the speed and rotating the knob to the left
decreases the speed. The current setting is shown on the display over
the word Cycle. An example of the suction rhythm (cycle) is when the
soft silicone breast cup collapses around the areola (dark area behind
your nipple) and releases. This can be related to how many times your
baby sucks per minute.
The slowest suction rhythm (cycle) is with a cycle speed of 1 (one).
This provides the fewest compressions per minute. A cycle speed of
30 (thirty) provides the greatest number of compressions per minute
and is the most comfortable setting. The suction rhythm (cycle) also
determines how long the suction strength (vacuum) is applied to
your breast. For example, a slow suction rhythm (cycle) would apply
suction strength (vacuum) for a slightly longer period of time. A faster
suction rhythm (cycle) would apply suction strength (vacuum) for
a shorter period of time (more comfortable). Adjust the cycle speed
only after you have used the pump 2-3 times and feel comfortable
with your Joy breast pump. The cycle speed is used to ne-tune the
suction rhythm to best mimic your baby’s suckling.
