Guidance and manufacturer´s declaration – electromagnetic immunity
a) Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be
considered. If the measured fi eld 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 reorienting or relocating the device.
b) Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.

At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propaga-
tion is affected by absorption and refl ection from structures, objects and
people.
Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the device, 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 to 800 MHz
d = 2.3 √P
800 MHz to 2.5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in metres (m).
Field strengths from fi xed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in
each frequency range.
