the user of the Philips
Avent breast pump
requires continued
operation during power
mains interruptions,
it is recommended
that the Philips Avent
breast pump be
powered from an
uninterruptible power
supply or a battery.
Interruptible electric
supply can cause the
breast pump to turn
off. This is acceptable
as this will not lead to
unacceptable risks.
