NOTE 1 At 80 MHz and 800 MHz, 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 PO3M is used exceeds
the applicable RF compliance level above, the PO3M should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the [PO3M].
B) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,a should
be less than the compliance level in
each frequency range.b
Interference may occur in the vicinity
