Guidelines and Manufacturer´s Declaration - Immunity
The ATMOS
®
E 341 Battery is intended for use in the electromagnetic environment specified below. The
customer or user of the ATMOS
®
E 341 Battery should ensure that it is used in such an environment.

Field strengths from fixed transmitters, as
determined by an electromagnetic site (a)
survey, should be less than the compliance
level (b).

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
®
E 341 Battery is used
exceeds the above compliance level, the ATMOS
®
E 341 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 should be below 3 V/m.
The device may not be used directly next to other devices or piled up with other devices. If operation next
to or piled with other devices is necessary, please watch the device to check its intended operation in this
arrangement.
Recommended separations between portable and mobile RF
Communications equipment and the ATMOS
®
E 341 Battery
The ATMOS
®
E 341 Battery is intended for use in electromagnetic environment in which radiated
disturbances are controlled. The customer or user of the ATMOS
®
E 341 Battery can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
Communications equipment and the ATMOS
®
E 341 Battery as recommended below, according to the
maximum output power of the communications equipment.
