Guidance and manufacturer’s declaration – electromagnetic immunity
The NasoNeb Compressor is intended for use in the electromagnetic environment specified below. The customer
or the user of the NasoNeb Compressor should assure that it is used in such an environment.

Portable and mobile RF communications
should be used no closer to any part of the
NasoNeb Compressor, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
80 MHz to 800 MHz
800 MHz to 2.5 GHz
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).
b
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:
NOTE 1. At 80 MHz and 800 MHz, 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,
object 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 NasoNeb Compressor is used exceeds the applicable RF compliance level above, the NasoNeb Compressor should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re¬orienting or relocating the NasoNeb Compressor
b
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m
