equipment should be used no closer to
any part of the ECO 3 EXPERT,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
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 ECO 3 EXPERT is used
exceeds the applicable RF compliance level above, the ECO 3 EXPERT should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the ECO 3 EXPERT.
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 ECO 3 EXPERT
The ECO 3 EXPERT is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the ECO 3 EXPERT
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the ECO 3 EXPERT
