Useful information
• Stimulation should be at a comfortable vacuum level, pumping at a
level that is too high is not necessary.
• Reassess your Maximum Comfort Vacuum throughout your pumping
experience. It can change throughout each stage of lactation.
• The pump unit will work even if the battery is drained when
connected to the external power adaptor. Charge the battery before
pumping on battery power.
)
• Your breast pump contains a built-in (non-replaceable) lithium-ion
rechargeable battery. Carrying such batteries on airplanes may be
restricted by the country you are visiting. Please consult with the coun-
try you are visiting to find out if there are any restrictions that pertain
to traveling with lithium-ion batteries.
• Unplugging the power adaptor from the wall outlet (mains) is
considered the disconnection of the device.
