Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the Philips Avent breast pump is used exceeds the applicable RF compliance level
above, the Philips Avent breast pump should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating
the Philips Avent breast pump.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
Recommended separation distances between portable and mobile RF communications equipment
and the Philips Avent breast pump
The Philips Avent breast pump is intended for use in a home healthcare environment in which
radiated RF disturbances are not controlled
The user of the Philips Avent breast pump can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Philips Avent breast pump as recommended below, according to the maximum
output power of the communications equipment.

3 Vrms Portable and mobile RF communications equipment should
be used no closer to any part of the Philips Avent breast
pump, including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.Recommended separation
distance d=1,17 √P The breast pump can be turned off.
3 V/m 80 MHz to 800 Mhz d=1,17 √P 800 MHz to 2,5 GHz d=2,33 √P
where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer and
d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey, should be less than the
compliance level in each frequency range. Interference may
occur in the vicinity of equipment marked with the following
symbol:
with applicable EMC directives, it may still be susceptible
to excessive emissions and/or may interfere with other
equipment. A consequence can be that the breast pump turns
off or the on/off button starts flashing (see troubleshooting for
more information), which is acceptable as this will not lead to
unacceptable risks. To prevent interference, keep other electric
equipment away from the breast pump during expressing.
Caution: Although the breast pump is compliant
