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 xed 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 o or the on/o button starts ashing
(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.
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 aected by
absorption and reection from structures, objects and people.
Field strengths from xed 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 xed RF transmitters,
an electromagnetic site survey should be considered. If the measured eld 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, eld 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.
