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.
80 MHz to 800 Mhz d=1,17 √P
3 V/m
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.
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.
