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 ME Equipment is used exceeds the applicable RF compliance level above, the ME Equipment should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the ME Equipment.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
