NOTE 1 With 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of electromagnetic sizes is
influenced by absorptions and reflections of buildings, objects and people.
a The field strength of stationary transmitters, such as base stations of cellular phones and mobile terrain radio
equipment, amateur radio transmitters, cbm broadcast and TV stations cannot be predestined exactly.
To determine the electromagnetic environment in regard to stationary transmitters, a study of the location is to
be considered. If the measured field strength at the location where the ATMOS
is used exceeds the above compliance level, the ATMOS
verify the intended use. If abnormal performance characteristics are noted, additional measures might
be necessary, e. g. a changed arrangement or another location for the device.
b Within the frequency range of 150 kHz to 80 MHz the field strength is to be below 3 V/m.

For transmitters for which the maximum nominal output isn´t indicated in the above table, the recommended
separation distance d in meters (m) can be determined using the equation belonging to the respective column
whereas P is the maximum nominal output of the transmitter in watts (W) acc. to manufacturer´s specification.
