Notes on EMC
14.3 Guidelines and Manufacturer´s Declaration - Immunity
The ATMOS
®
A / C 161 Battery is intended for use in the electromagnetic environment specified below. The customer
or user of the ATMOS
®
C 161 should ensure that it is used in such an environment.

Field strengths from fixed transmitters, as
determined by an electromagnetic site (

survey, should be less than the compli-

3 V/m
80 MHz bis 2,5 GHz 10 V/m
NOTE 1 With 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2 These guidelines might not be applicable in any 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 is to
be considered. If the measured field strength at the location where the ATMOS
®
A / C 161 Battery is used
exceeds the above compliance level, the ATMOS
®
A / C 161 Battery 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 device.
b Within the frequency range of 150 kHz to 80 MHz the field strength is to be below 3 V/m.
