Electromagnetic Immunity
Electromagnetic Immunity
Savina is intended for use in the electromagnetic environment specified below. The operator should assure
that is used in such an environment.

X1
:
For P
EIRP
the highest possible "equivalent isotropic radiated power" of the adjacent RF transmitter has
to be inserted (value in Watt). Also in the vicinity of equipment marked with the symbol
interference may occur. Field strengths from fixed, portable or mobile RF transmitters at the
location of Savina should be less than 3 V/m in the frequency range from 150 kHz to 2.5 GHz and
less than 1 V/m above 2.5 GHz.

ISM bands in this frequency range are: 6.765 MHz - 6.795 MHz, 13.553 MHz - 13.567 MHz, 26.957
MHz - 27.283 MHz, 40.66 MHz - 40.70 MHz.
