Guidance and manufacturer’s declaration – electromagnetic immunity
M102 Mesh Nebulizers are intended for use in the electromagnetic
environment specified below. The customer or the user of these
YUWELLNebulizers should assure that it is used in such environment.

Portable and mobile RF communi-
cations equipment should be used
no closer to any part of the
YUWELLnebulizer M102 including
cables, than the recommended
separation distance calculated from
the equation appropriate to the
frequency of the transmitter.
Recommend separation distance
d=1.2
d=1.2 80MHz to 800 MHz
d=2.3 800 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 meters (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. b
Interference may occur in the
vicinity of equipment marked
with he following symbol:
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: 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 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 M102&M103are
used exceeds the applicable RF compliance level above, the M102
should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as
reorienting or relocating the Nebulizer.
b) Over the frequency range 150 kHz to 80MHz, field strengths should
be less than 3 V/m.
