(b)
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency
range 80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications
equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in
these frequency ranges.
(c)
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 pump is used exceeds the applicable RF compliance level above, the pump should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the pump.
(d)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
