Guidance and manufacturer’s declaration - electromagnetic immunity
The RadiForce series is intended for use in the electromagnetic environment specified below. The customer
or the user of the RadiForce series should assure that it is used in such an environment.

the RadiForce series, including
cables, than the recommended

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. 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 RadiForce series is used exceeds the applicable RF compliance level above, the RadiForce series should
be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the RadiForce series.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
