Guidance and manufacturer’s declaration – electromagnetic immunity
The MC
2
Series is intended for use in the electromagnetic environment specified below. The
customer or the user of the MC
2
Series should assure that it is used in such an environment.

Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due
to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the MC
2
Series is used exceeds the applicable RF
compliance level above, the MC
2
Series should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the MC
2
Series.
