Radiated RF 10V/m
IEC61000-4-3
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 affected by
absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
a
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 device is used exceeds the applicable RF compliance level above, the device
should be observed to verify normal operation. If abnormal performance is observed, additional mea-
sures may be necessary, such as re-orienting or relocating the device
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

in watts (W) according to the
transmitter manufacturer, d is the
recommended separation distance
in meters (m) Field strengths from
fixed RF transmitters, as deter-
mined by an electromagnetic site
survey ,should be less than the
