Recommended separations between portable and mobile RF Communications
equipment and the ENT-camera ATMOS
®
A / C 161 / 261 Aspirator
The ATMOS
®
A / C 161 / 261 Aspirator is intended for use in electromagnetic environment in which ratiated distur-
bances are controlled. The customer or user of the ATMOS
®
C 161 Aspirator can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF Communications equipment and
the ATMOS
®
A / C 161 / 261 Aspirator as recommended below, according to the maximum output power of the
communications equipment.

For transmitters for which the maximum nominal output isn´t indicated in the above table, the recommended sepa-
ration 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 don´t like to be applicable in any case. The propagation of electromagnetic sizes is
influenced by absorptions and reflections of buildings, objects and peopl
