Radiated RF IEC 61000-4-3
6Vrms in ISM bands
between 150KHZ to
80MHz
10 V/m
80 MHz to 2.7 GHz
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation
distance:
d = 1.2ÖP
d = 1.2ÖP 80 MHz to 800 MHz
d = 2.3ÖP 800 MHz to 2.7 GHz
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 in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked with
the following symbol.
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, the field strengths should be less than 3 V/m.
