It is possible to check
the interference close
to the appliances labelled
with the following symbol:
Note 1:
At 80 MHz and 800 MHz the highest frequency range applies.
Note 2:
These guidelines could not apply to all conditions. The electromagnetic propa-
gation is affected by the absorption and reflection of premises, objects and individuals.
a.
The field strengths for fixed transmitters like base stations of radiotelephones (mobiles
and cordless) and terrestrial mobile radio networks, amateur radio appliances, AM and FM
radio transmitters and TV transmitters cannot be theoretically and accurately predicted.
In order to determine an electromagnetic environment caused by fixed RF transmitters,
an electromagnetic survey of the site should be taken into account. If the field strength
measured in the place where the Mistral appliance is used exceeds the applicable level
of conformity hereinabove, the normal operation of the appliance should be kept under
watch. If abnormal performances are noted, additional measures could be necessary, such
as a different direction or positioning of the appliance.
b.
The field strength on a frequency range between 150 kHz and 80 MHz should be less
than 10 V/m.
Recommended separation distances between portable and mobile radio communi-
cation appliances and the monitor
The Mistral aerosol is designed to operate in an electromagnetic environment in which the
RF radiated interferences are kept under control. The customer or the user of the Mistral
appliance can contribute to prevent electromagnetic interferences by ensuring a minimum
distance between portable and mobile RF communication devices (transmitters) and the
Mistral appliance as recommended below, according to the maximum rated output power
of the radio communication devices.

The recommended separation distance
d
in meters (m) for transmitters with maximum
rated output power not specified above can be calculated from the equation applicable
to the frequency of the transmitter, in which
P
is the maximum rated output power of the
transmitter in Watt (W) according to the manufacturer of the transmitter.
Note 1:
At 80 MHz and 800 MHz the separation distance for the highest frequency range
applies.
Note 2:
These guidelines could not apply to all conditions. The electromagnetic propa-
gation is affected by the absorption and reflection of premises, objects and individuals.
