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 radio, 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 MicroRPM is used
exceeds the applicable RF compliance level above, the MicroRPM should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orientating or relocating
the MicroRPM.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m
Recommended separation distances between portable and mobile RF
communications equipment and the MicroRPM
The MicroRPM is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
MicroRPM can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the MicroRPM as recommended below,
according to the maximum output power of the communications equipment

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated using
the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in Watts (W) according to
the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.

propagation is affected by absorption and reflection from structures objects
and people.
