EMC Information
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.

Portable and mobile RF communications
equipment should be used no closer to any part
of the RadiForce series, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

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.
