P is the nominal power of the transmitter in watt (W)
according to the specifications of the transmitter
manufacturer; d is the recommended safety distance
in meters (m).
The field strength of stationary transmitters should be
lower than the accordance level for all frequencies
according to a testing on location.
Disturbances are possible near devices with the
following symbol:
NOTE 1: For 80 Hz and 800 MHz the higher frequency range is valid.
NOTE 2: These guidelines may not be applicable for all cases. The propagation of electromagnetic values is influenced
by absorptions and reflections of buildings, objects and people.
a
The field strength of stationary transmitters such as fixed parts of cellular phones and mobile radio sets, amateur radio
stations, AM and FM radio and television cannot be determined exactly in theory. To detect the electromagnetic
environment in regard to stationary transmitters a study of the location should be considered. If the measured field
strength at the location where
“
LactoFAN2
”
is being used exceeds the accordance level above the
“
LactoFAN2
”
should be watched to verify the proper functions. If unusual features are watched additional actions might be
necessary such as a modified orientation or another location of the

”
is intended for use in an electromagnetic environment with controlled HF disturbances. The user of
the
“LactoFAN2”
can help to avoid electromagnetic disturbances by keeping the minimum distance between portable
and mobile telecommunication devices (transmitters) and the
