Electromagnetic
environment – guidance
Floors should be wood, concrete
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be
at least 30 %.
Mains power quality should be
that of a typical residential or
hospital environment.
Mains power quality should be
that of a typical residential or
hospital environment.
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.
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a
typical residential or hospital
environment.
