Atmos S 201 Thorax Operating Instructions Manual page 46

NOTE 1 By 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2 These guidelines might not be applicable in all cases. The emanation of electromagnetic waves is affected by
absorption and reflection 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
the above compliance level, the ATMOS
performance characteristics are noted, additional measures might be necessary, e. g. a changed arrangement or
another location for the ATMOS
b Over the frequency range of 150 kHz to 80 MHz, field strengths should be lower than 3 V/m.
Recommended separations between portable and mobile
RF Communications equipment and the ATMOS
The ATMOS
®
disturbances are controlled. The customer or user of the ATMOS
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF Communications equipment and the ATMOS
according to the maximum output power of the communications equipment.

For transmitters for which the maximum nominal output is not indicated in the above table, the recommended safety
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.
