WARNING: Portable RF communications equipment (including peripherals
such as antenna cables and external antennas) should be used no closer
than 30 cm (12 inches) to any part of Elvie Stride including cables specified
by the manufacturer. Otherwise, degradation of the performance of this
equipment could result

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, a should be less than the compliance level in each
frequency range. Interference may occur in the vicinity of equipment marked with the
following symbol.
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
A. 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 breast pump is used exceeds the applicable RF compliance level above, the 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
breast pump.
B. Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than 10 V/m.
