The electromagnetic field strengths of fixed radiofrequency emitters, as determined by an electromagnetic environment measurement (a),
must be less than the compliance level in each frequency range (b).
Interference may occur near equipment marked with the symbol below:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These specifications may not be applicable in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and persons.
(a): The electromagnetic field strengths of fixed radiofrequency emitters, such as base stations for
mobile telephones (cellular/cordless), mobile radios, amateur radio, AM/FM radio broadcasts
and TV broadcasts cannot be determined exactly by theory. To assess the electromagnetic
environment due to fixed radiofrequency emitters, an electromagnetic environment
measurement must be made. If the measured radiofrequency field strength in the immediate
environment where the product is used exceeds the compliance level specified above, the
performance of the product must be tested to verify whether it conforms to the specification.
If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the product.
(b): In the 150 kHz to 80 MHz frequency range, the electromagnetic field strengths must be less
than 3 V/m.
