Table 4 Recommended separation distances
Device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customers or the users of these YUWELL Nebulizers
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and The
involved model
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 meters (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: At 80MHz and 800MHz, the separation distance for the higher frequency range
applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.

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 involvedmodel
is used
exceeds the applicable RF compliance level above, the model 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.
