Radiated RF 10 V/m
IEC 61000-4-3 80 MHz to 2.7 GHz
80% AM at 1kHz
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.
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 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 measures may be necessary, such as re-orienting
or relocating the device.
B Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.

Where, P is the maximum
output power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation
distance.
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site
survey, should be less than
the compliance level in each
frequency range.
