NOTE 1 At 80 MHz and 800 MHz, the higher fre
quency range applies.
NOTE 2 These guidelines may not apply in all situa
tions. 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) telepho
nes 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 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 mea
