Table 204:
The NeuroTrac® product is intended for use in the electromagnetic environment
specifi ed below. The customer or the user of the NeuroTrac® product should assure
that it is used in such an environment.

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
aff ected by absorption and refl ection from structures, objects and people.
a Field strengths from fi xed 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 en-
vironment due to fi xed RF transmitters, an electromagnetic site survey should be considered.
If the measured fi eld strength in the location in which NeuroTrac® product is used exceeds
the applicable RF compliance level above, the NeuroTrac® product should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the NeuroTrac® product.
b Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.

Electromagnetic environment
guidance
Portable and mobile RF communications
equipment should be used no closer
to any part of the NeuroTrac®product,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
d = 1.2 √P 150 kHz to 80 MHz,
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5GHz
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 fi xed RF transmitters,
as determined by an electromagnetic site
a
survey , should be less than the compli-
ance level in each frequency range b .
