Guidance and manufacturer's declaration - electromagnetic immunity
The above listed models are intended for use in the electromagnetic environment specified below. The customer or the
user of the above listed models should assure that they are used in such an environment.

Portable and mobile RF communications
equipment should not be used no closer to
any part of the above listed models,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1,2√P
d = 1,2√P 80 MHz - 800 MHz
d = 2,3√P 800 MHz – 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 a should be
less than the compliance level in each
frequency range. (b)
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, 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 above listed models are used, exceeds the applicable RF compliance level above, the
above listed models should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the above listed models.
b)
c)
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283
MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7
MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and
50,0 MHz to 54,0 MHz.
