Table 15. 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 ensure that it is used in such an environment.
IMMUNITY TESTS
Radiated RF
IEC 61000-4-3
Note: Ut is the AC mains voltage prior to application of the test level.
At 80 MHz and 800 MHz, the higher frequency range applies.
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
system is used exceeds the applicable RF compliance level above, the system should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the system.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
