(a): The electromagnetic field strength of fixed radiofrequency emitters, such as base stations for mobile telephones (cellular/cordless), mobile 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.
