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/wireless) 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 F15 Series Fetal & Maternal Monitors are used exceeds the applicable RF
compliance level above, the F15 Series Fetal & Maternal Monitors should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the F15 Series Fetal & Maternal Monitors.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
c) The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz
to6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70
MHz. The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz, 3.5 MHz to
4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15 MHz, 14 MHz to 14.2 MHz,
18.07 MHz to 18.17 MHz,21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99 MHz, 28.0 MHz to 29.7 MHz
and 50.0 MHz to 54.0 MHz.
