Recommended separations between portable and mobile RF Communications
equipment and the ATMOS
®
A / C 161 Battery
The ATMOS
®
A / C 161 Battery is intended for use in electromagnetic environment in which radiated disturbances
are controlled. The customer or user of the ATMOS
®
A / C 161 Battery can help prevent electromagnetic interfe-
rence by maintaining a minimum distance between portable and mobile RF Communications equipment and the
ATMOS
®
A / C 161 Battery as recommended below, according to the maximum output power of the communica-
tions equipment.

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