Recommended separation distances between portable and mobile
RF communications equipment and the NasoNeb Compressor
The NasoNeb Compressor is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the NasoNeb Compressor
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the NasoNeb
Compressor as recommended below, according to the maximum output power of the
communications equipment

For transmitters rated at a maximum output not listed above, the recommended separation distance d
in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
Note 1. At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
