Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1:
At 80MHz and 800MHz, 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 150kHz and 80MHz are 6.765MHz to 6.795MHz, 13.553MHz to
13.567MHz, 26.957MHz to 27.283MHz and 40.66MHz to 40.70MHz.
b
The compliance levels in the ISM frequency bands between 150kHz and 80MHz and in the frequency range 80MHz to 2.5GHz 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

Over the frequency range 150kHz to 80MHz, field strengths should be less than 10V/m.
