Interference may occur in the vicinity of

NOTE 1) At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2) These guidelines may not apply in all situatio Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and

a
Field strengths from fixed transmitters, such as base tations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM
radio broadcast and TV broadcast cannot be predicted theoretically with accurac
y.
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 E
UT 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.

Over the frequency range 150kHz to 80MHz, field strengths should be less than
