37 Notes on EMC
Guidelines and Manufacturer´s Declaration - Immunity
The ATMOS® Cam 21 / 31 is intended for use in the electromagnetic environment
specified below. The customer or user of the ATMOS® Cam 21 / 31 should ensure that it
is used in such an environment.

Portable and mobile
communications equipment
should be separated from the
ATMOS® Cam 21 / 31
incl. the cables
by no less than the distances
calculated/listed below.
Recommended distances:
d = 1.17*sqrt(P)
d = 1.17*sqrt(P) for 80 MHz to 800
MHz
d = 2.33*sqrt(P) for 800 MHz to 2.5
GHz
where „P“ is the max. power in watts
(W) and d is the recommended
separation distance in meters (m).
Field strengths from fixed
transmitters, as determined by
an electromagnetic site (a) survey,
should be less than the compliance
level (b).
Interference may occur in the vicinity
of equipment containing following
symbol:
Radiated RF IEC

3 V/m
80 MHz to 2.5 GHz 3 V/m
80 MHz to 2.5 GHz
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 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® Cam 21 / 31 is used exceeds the above
compliance level, the ATMOS® Cam 21 / 31 is to be observed to 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 ATMOS® Cam 21 / 31.
b Over the frequency range of 150 kHz to 80 MHz, field strengths should be lower than 3 V/m.
