Electromagnetic environment - guidelines
Portable and mobile radio equipment should not
be used in closer proximity with the nebulizer MN-
300/8 (including power cord) than the
recommended safety distance. That distance is
calculated according to the equation appropriate
to the transmission frequency.
Recommended safety distance:
Conducted RF

80 MHz to 2.5 GHz
3 V/m
D = 1.2√P 80 MHz to 800 MHz
D = 2.3√P 800 MHz to 2.5 GHz
Where P is the rated output of the transmitter in
watts (W) as
stated by the transmitter manufacturer and D is
the recommended safe distance in meters (m).
The field strength of fixed radio transmitters at all
frequencies should be below the compliance level
based on on-site measurements.
a b
Interference is possible in the vicinity of
equipment that carries the following icon.
NOTE 1: At 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2: This guideline may not be applicable in all cases. The propagation of electromagnetic energy is affected by absorption
and reflection by buildings, objects and people.
a
The theoretical field strength of fixed transmitters such as radio telephone and mobile agricultural radio equipment base
stations, amateur radio transmitters, AM and FM radio and TV transmitters cannot be precisely determined in advance. In order to
determine the electromagnetic environment with respect to fixed transmitters, a study of the location should be considered. If the
measured field strength at the location of the nebulizer MN-300/8 exceeds the compliance levels, the nebulizer MN-300/8 should be
observed to verify that it is FUNCTIONING as intended. If unusual performance characteristics are observed, additional measures
may be required such as modifying or changing the location of the nebulizer MN-300/8.
b
Above the frequency range of 150 kHz to 80 MHz. the field strength should be less than 3 V/m.
