should be less than the compliance level in each
frequency range. 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 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 150kHz to 80MHz, field strengths should be less than
3V/m.
