level in each
frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol :
NOTE 1 ) At 80MHz 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 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 EUT is used exceeds the applicable RF compliance level
above, the EUT should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the EUT.
b
Over the frequency range 150kHz to 80MHz, field strengths should be less than [V
