The electromagnetic field strengths of fixed radio frequency transmitters, as determined by an
electromagnetic environment measurement (a), shall be less than the compliance level for each
frequency range. Interference may occur near equipment identified by the following symbol:
Note: These specifications may not apply in all situations. Electromagnetic propagation is affected by
the absorption and reflection of structures, objects and people.
(a) The intensities of the electromagnetic fields of fixed radio frequency transmitters, such as base
stations for mobile (cellular / wireless) telephones, mobile radios, radio amateurs, AM / FM radio
transmissions and TV transmissions cannot be accurately determined theoretically. To evaluate the
electromagnetic environment due to fixed radio frequency transmitters, an electromagnetic
environment measurement must be performed. If the measured RF field strength in the immediate
environment of use of the product exceeds the radio frequency compliance level (specified above), it
is necessary to test the product performance to verify that it conforms to the specifications. If
