FSD complies with international standards for:
Electromagnetic Immunity Levels (2).
FSD is intended for use in the electromagnetic environment specified below. The customer or the user of the FSD
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 FSD, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

Where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from fixed R F transmitters, as
determined by an electromagnetic site surveya
should be less than the compliance level in each
frequency ranged.
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 FSD is used exceeds
the applicable RF compliance level above, the FSD should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the FSD.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
