Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
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 product is used exceeds the applicable RF compliance level above, the
product should be observed to verify normal operation. If abnormal performance is observed, addi-
tional measures may be necessary, such as re-orienting or relocating the product.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [U
1
] V/m = 3 V/m.
