iSE Series Electrocardiograph 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.
Field strengths from fixed transmitters, such as base stations for radio
a
(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 iSE is used exceeds the applicable RF compliance
level above, the iSE should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
reorienting or relocating the iSE.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than

The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz

are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283
