Radiated RF
IEC 61000-4-3
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, people and animals.
(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 product is used exceeds the applicable RF compliance
level above, the product should be observed, additional measures may be necessary, such as reorienting or relocating the product.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
10.3 Recommended Separation Distances between portable and mobile HFcommunications equipment and the product
The product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the product can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the product – according on output power and frequency of the communications equipment – as recommended in the following table.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency
of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800MHz, 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, people and animals.

Portable and mobile RF communications equipment should be used no closer to any part
of the product, including cables, than the recommended separation distance calculated
from the equiation applicable to the frequency of the transmitter.
Recommended separation distance :
d = 1.2√P d = 1.2√P for 80MHz to 800MHZ
for 800 MHz to 2.5 GHz
where P is the maximum output power rating of the transmitter in Watt (W) according to
the transmitter manufacturer and d is the re-commended separation distance in meters
(m) Field strengths from fixed RF transmitters, as determined by an electromagnetic site
survey(a), should be less than the compliance
