a. The field strengths for fixed transmitters like base stations of radiotelephones (mobiles and cord-
less) and terrestrial mobile radio networks, amateur radio appliances, AM and FM radio transmit-
ters 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 Eolo 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 communication ap-
pliances and the monitor
The Eolo 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 Eolo appliance can contribute to
prevent electromagnetic interferences by ensuring a minimum distance between portable and mobile
RF communication devices (transmitters) and the Eolo 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 propagation is affect-
ed by the absorption and reflection of premises, objects and individuals.
