Guidance and manufacturer's declaration - electromagnetic immunity
The unit is intended for use in the electromagnetic environment specified below. The user of the unit should ensure that it is
used in such an environment.

The field strengths of fixed transmitters, as deter-
mined by an electromagnetic site survey should be
below the compliance level in each frequency
range.

Note: These guidelines may not apply in all cases. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a)
The ISM bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz, 13.553 MHz to 13.567 MHz, 26.957 MHz to
27.283
MHz and 40.66 MHz to 40.7 MHz.
b)
The field strengths of fixed transmitters, such as base stations for radio (cellular/cordless) telephones and terrestrial radio
units, amateur radio stations, AM and FM radio and TV channels cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment with regard to fixed transmitters, a site inspection should be considered. If the field
strength measured at the site where the unit is used exceeds the abovementioned compliance level, the unit must be moni
-
tored to ensure it is functioning properly. In the event of any unusual operating behavior, additional measures may be
required, such as changing the orientation or location of the unit.
