Table 204:
The NeuroTrac™ product is intended for use in the electromagnetic environment
specified 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
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 broad�
cast cannot be predicted theoretically with accuracy. To assess the electromagnetic environ�
ment due to fixed RF transmitters, an electromagnetic site survey should be considered. If
the measured field 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, field strengths should be less than 3 V/m.
