Recommended separations between portable and mobile RF Communications
equipment and the ATMOS
®
Aqua clean
The ATMOS
®
Aqua clean is intended for use in electromagnetic environment in which radiated disturbances are
controlled. The customer or user of the ATMOS
®
Aqua clean can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF Communications equipment and the ATMOS
®
Aqua clean as recommended below, according to the maximum output power of the communications 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.

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
®
Aqua clean is used exceeds
the above compliance level, the ATMOS
®
Aqua clean 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.
