Guidance and manufacturer's declaration – electromagnetic immunity
The system is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should assure that it is used in such an environment.
Immunity test
Conducted Radio
Frequency
IEC 61000-4-6
Radiated Radio
Frequency
IEC 61000-4-3
Note 1: At 80 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
