Mains power quality
should be that of a
typical commercial or
hospital environment.
If the user of the
electric breastpump
Lactina requires
continued operation
during power mains
interruptions, it is
recommended that
the electric breast-
pump Lactina is
powered from an
uninterruptible power
supply or a battery.
Power frequency
magnetic fields should
be at levels charac-
teristic of a typical
location in a typical
commercial or hospi-
tal environment.
