Disruptions are possi-
ble near devices that
carry the following
symbol:
• REMARK 1: The higher value will apply at 80 MHz and 800 MHz.
• REMARK 2: These Guidelines may not apply to all situations. The disper-
sion of electromagnetic waves is influenced by absorption and reflec-
tions from buildings, objects and people.
a. The field strength of stationary transmitters, such as base stations of radio
telephones, mobile broadcasts for rural areas, amateur stations, and AM and
FM radio transmitters, cannot be precisely predetermined theoretically. An
investigation of the location is recommended, to ascertain the electromagnetic
environment as a result of stationary high frequency transmitters. If the field
strength of the device exceeds the level of agreement given above, the device
must be observed with regard to its normal operation at each place of use. In
case of unusual performance characteristics, it can be necessary to take
additional measures, such as the re-orientation of the device, for example.
b. The field strength will be lower than 3 V/m above the frequency range from
150 kHz to 80 MHz.
