Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
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 af-
fected by absorption and reflection from structures, objects and people.
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 broad-
cast cannot be predicted theoretically with accuracy. To assess the electromagnetic environ-
ment 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, additional measures may be necessary, such as reorient-
ing or relocating the product.
