nterference may occur in the vicinity of
equipment marked with the following symbol:
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
