Mains power quality should be that
of a typical commercial or hospital
environment.
If the user of the electric breast
pump Freestyle requires continued
operation during power mains in-
terruptions, it is recommended that
the electric breast pump Freestyle
is powered from an uninterruptible
power supply or a battery.
Power frequency

magnetic field
IEC 61000-4-8
3 A/m 3 A/m Power frequency magnetic fields
should be at levels characteristic of
a typical location in a typical com-
mercial or hospital environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
