The magnetic field with the feeder frequency should have the

environment.

Portable radio communication devices should not be used in
the vicinity of any part of the nebulizer, including cables, at a
distance shorter than the recommended one, calculated based
on the relevant equation matching the transmitter frequency.
Recommended distance:
d = 1,2√P
d = 1,2√P 80 MHz do 800 MHz
d = 2,3√P 800 MHz do 2,5 GHz
where P is the maximum rated output power of transmitters in
watts (W) specified by the transmitter manufacturer and d is the
recommended distance in meters (m).
The field strength of the constant radio transmitters determined by
measuring the background electromagnetic interference should be
lower than the conformity level for every frequency range. The
interference may occur near devices marked with the following
symbol:

PLEASE NOTE! For 80 MHz and 800, a higher frequency range applies.
PLEASE NOTE! These guidelines may not apply in certain cases. Electromagnetic wave propagation changes as a result of absorption and reflections from structures,
objects and people.
1.
It is not possible to determine the strength of the field from permanent transmitters, including base transceiver stations (for mobile/wireless networks), portable
terrestrial transceivers and amateur radio transceivers, AM and FM radio transceivers and TV transceivers. To determine the electromagnetic conditions relating to
permanent radio transceivers, electromagnetic interference in the location should be measured. If the measured field strength in the location where the nebulizer
is used exceeds the applicable conformity level specified above, the nebulizer should be watched to verify its correct operation. If you notice any extraordinary
operation, some extra measures may be required, including e.g. nebulizer reorientation or relocation.
2.
For the frequency range 150 kHz to 80 MHz, the field strength should be below 3 V/m.

Recommended distance between portable radio
communication devices and the nebulizer
The nebulizer is designed for use in an electromagnetic
environment with limited interference caused by
radio waves. The nebulizer user may help to reduce
electromagnetic interference by ensuring the minimum
distance between the mobile radio communication devices
(transmitters) and the nebulizer as specified below, as
appropriate for the maximum rated output power of the
communication device.
For transmitters for which the maximum rated output power
was not mentioned above, the recommended distance d in
meters (m) may be estimated by the equation appropriate
for the transmitter frequency, where P is the maximum
output rated power of transmitters in watts (W) specified
by the transmitter manufacturer.
