Manual URYXXON
The field intensity of stationary transmitter, e.g. base stations for cordless telephones and mo-
a
bile radio equipment, amateur radio stations, AM and FM radio and television station, can not be
predestinated precisely. For the identification of the electromagnetic environment regarding the
stationary transmitter, a survey about the electromagnetic phenomena of area should be made.
If the measured field intensity at the place where URYXXON
compliance level mentioned in the list above, an extra observation of instrument is necessary as
an evidence for the conventional functionality. In the case that unusual performance features oc-
cur, additional actions like changing the direction of instrument or moving the URYXXON
to another place is necessary.
b Across the frequency range from 150 kHz to 80 MHz the field intensity should be lesser than
3 V/m.
Recommended protection ratio between portable and mobile RF-telecommunication
device and the URYXXON
The URYXXON Relax is destined for the use in electromagnetic environments where RF-dis-
®
turbances are controlled. The user of URYXXON
es by observing the minimum distance – dependent on the output power of telecommunication
device, see list below - between portable and mobile RF-telecommunication devices (transmit-
ter) and the URYXXON

For transmitters whose maximum rated power is not listed above, the recommended protection
ratio d in meter (m) can be calculated by using the equation from the particular column, where
as P is the maximum rated power of transmitter in watt (w) according to description of manufac-
turer.
ANNOTATION 1 In case of 80 MHz or 800 MHz the higher frequency rang is valid.
ANNOTATION 2 These guidelines are not applicable for all cases. The propagation of electro-
magnetic volumes is influenced by the absorbtion and reflection of buildings, items and humans.
