Guidance and manufacture’s declaration – electromagnetic immunity
The IO5000TA is intended for use in the electromagnetic environment specified below. The customer or the user of the
IO5000TA 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 IO5000TA,
including cables, than the recommended separation
distance calculated from the equation applications to
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 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by adsorption 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 IO5000TA is used exceeds the applicable RF
compliance level above, the IO5000TA should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the IO5000TA.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
