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 Ambistik PFT / Ambistik CPET is used exceeds the abovementioned
compliance levels, the Ambistik PFT / Ambistik CPET 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
Ambistik PFT / Ambistik CPET.
b)
Over the frequency range from 150 kHz to 80 MHz, the field strengths should be less than
3 V/m.
