The Product is intended for use in the electromagnetic environment specified below. The customer or the user of
the Product should assure that it is used in such an environment.
Immunity test

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.
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 Product is used exceeds the applicable RF compliance level above, the
Product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Product.
Over the frequency range 150 kHz to 80 MHz, field strenths should be less than [V1]V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of the Product, including cables, than the
recommeded 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) accordint to
the transmitter manufacturer and d is the
recommended separation distance in metres

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,"
should be less than the compliance level in
each frequency range."
