CADENCE II Fetal Monitor User Manual

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.
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 CADENCE II Fetal Monitor is used exceeds the applicable RF
compliance level above, the CADENCE II Fetal Monitor should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the CADENCE II Fetal Monitor.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
