Mains power quality
should be that of a
typical residential or
hospital environment. If
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.
