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/ The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to
6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
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 device is used exceeds the applicable RF compliance level
above, the device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the device.
d/ Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
