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 Corsia 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 Corsia 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 Corsia
appliance can contribute to prevent electromagnetic interferences by ensuring a minimum
distance between portable and mobile RF communication devices (transmitters) and the
Corsia 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 fre-
quency 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 propaga-
tion is affected by the absorption and reflection of premises, objects and individuals.
