N N o o t t e e - - At 80 MHz and 800 MHz, the higher frequency range applies.
N N o o t t e e - - 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 I I s s o o A A i i r r is used exceeds the applicable RF compliance
level above, I I s s o o A A i i r r should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating I I s s o o A A i i r r .
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of I I s s o o A A i i r r , including cables, than the
recommended separation distance calculated
from the equation appropriate for the
frequency of the transmitter.
Recommended Separation Distance
d=(0.35)√ P
80 MHz to 800 MHz
d=(0.70)√ P
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
