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:
Caution: Although the breast pump is compliant 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.
