P
is the maximum rated power of
the transmitter in watts (W)
according to the manufacturer's
specifications
and
d
is the recommended safety
distance in meters (m)
Field strengths from fixed RF
transmitters should be less than
the compliance level at all
frequencies according to on-site
investigations.
Interference may occur in the
environment of equipment marked
with the following symbol:
Note 1: The higher frequency range shall be used at 80 MHz and 800 MHz.
Note 2: These guidelines may not be applicable in all cases. The propagation of electromagnetic
parameters is influenced by absorptions and reflections from buildings, objects and people.
a)
The field strengths of stationary transmitters, such as base stations and mobile land-based
radios, amateur radio stations, AM and FM radio and television transmitters, can theoretically
not be predicted exactly. In order to determine the electromagnetic environment with regard
to the stationary transmitters, a study of the electromagnetic phenomena of the site should
be considered. If the measured field strength at the site where the Safestik is used exceeds
the abovementioned compliance levels, the Safestik should be observed to demonstrate its
intended function.
If unusual performance characteristics are observed, additional measures
may be required, such as a change in orientation or in location of the Safestik.
b)
Over the frequency range from 150 kHz to 80 MHz, the field strengths should be less than
3 V/m.
