should be used no closer to AVERO Premium
Plus, including cables, than the recommended
separation distance
calculated according to the applicable
transmission frequency.
Recommended separation distance
d=0.35√P
d=1.2√P 80 MHz to 800 MHz
d=2.3√P 800 MHz to 2.5 GHz
Where P is the nominal power of the transmitter in
watts (W) according to to the transmitter
manufacturer and d is the recommended
separation distance in meters (m).
Determines the field strength of stationary radio
transmitters
by electromagnetic location measurement,
a
–
should be less than the CONCORD level in all
frequency ranges.
b
In the vicinity of equipment marked with the
following
symbol interferences are possible:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These instructions cannot be applied in all situations under certain circumstances. The propagation of
electromagnetic waves is influenced by absorption and reflection from structures, objects and people.
a
The field strength of stationary transmitters, such as base stations of cordless telephones and land mobile radios,
amateur radio, AM and FM stations as well as radio and TV stations cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic survey site is
recommended. If the measured field strength in the environment in which the AVERO Premium Plus is to be used
exceeds the applicable RF compliance level, particular attention must be paid to be able to ensure the normal
operation of the AVERO Premium Plus. If abnormalities are observed, additional measures may be necessary, such
as reorienting or relocation of AVERO Premium Plus.
b
In the frequency range of 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
