This device is intended for operation in an electromagnetic environment in
which the radiated high frequency disturbance variables are monitored. The
user of the device can help to prevent electromagnetic disruptions by
maintaining the minimum distances between portable and mobile high
frequency communication equipment (transmitters) and the device as
recommended below, in accordance with the maximum output power of the
communications equipment.
REMARK 1: The higher value will apply at 80 MHz and 800 MHz.
REMARK 2: These Guidelines may not apply to all situations. The dispersion of electromagnetic
waves is influenced by absorption and reflections 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 elec-
tromagnetic 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.
