Recommended separation distances between portable and mobile RF
communication equipment and the Aerogen USB Controller System that is not life
supporting
The Aerogen USB Controller System is intended for use in the electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user
of the Aerogen USB Controller System can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Aerogen USB Controller System as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power 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.
