Table 15.
Guidance and manufacturer's declaration - electromagnetic immunity
The Aerogen USB Controller system is intended for use in the electromagnetic
environment specified below. The customer or the user of the Aerogen USB Controller
system should assure that it is used in such an environment.
Immunity Test
Conducted RF
IEC/EN 61000-4-6
Radiated RF
IEC/EN 61000-4-3
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.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due
to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the Aerogen USB Controller system is used exceeds the applicable
RF compliance level above, the Aerogen USB Controller system should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orientating or relocating the Aerogen USB Controller system.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m

Electromagnetic
Environment - Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part
of the Aerogen USB Controller
system, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended Separation Distance
d = [1.17] √P
d = [1.17] √P... 80MHz to 800MHz
d = [2.33] √P... 800MHz to 2.5GHz
where P is the maximum output
power rating of the transmitter
in Watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in
metres (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,ª should be
less than the compliance level in each
frequency range.
Interference may occur in the vicinity
of equipment marked with the
following symbol:
