Guidance and manufacture’s declaration – electromagnetic immunity
The CIRCULATION PRO is intended for use in the electromagnetic environment specified below. The
customer or the user should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the ELECTRO FLEX, including cables,
than the recommended separation distance

the frequency of the transmitter.

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 of
equipment marked with the following
symbol:
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.
a 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 CIRCULATION PRO is
used exceeds the applicable RF compliance level above, the CIRCULATION PRO should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the CIRCULATION PRO.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
