Atmos C 051 Thorax Operating Instructions Manual page 45

NOTE 1 With 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2 These guidelines may not be applicable in every case. 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 must be considered. If the measured field strength at the location where the
ATMOS® C 051 Thorax is used exceeds the above compliance level, the ATMOS
observed to verify the intended use.
If abnormal performance characteristics are noted, additional measures could 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 must be below 3 V/m.
13.4 Recommended separations between portable and mobile
RF Communications equipment and the ATMOS
The ATMOS C 051 Thorax is intended for use in electromagnetic environment in which radiated disturbances
®
are controlled. The customer or user of the ATMOS
rence by maintaining a minimum distance between portable and mobile RF Communications equipment and
the ATMOS C 051 Thorax as recommended below, according to the maximum output power of the communi-
®
cations equipment.

For transmitters for which the maximum nominal output isn´t indicated in the above table, the recommen-
ded separation distanced 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.
