– electromagnetic immunity

The NeuroTrac™ product is intended for use in the electromagnetic environment

specied below. The customer or the user of the NeuroTrac™ product 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

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) ac�

cording to the transmitter manufacturer

and d is the recommended separation

distance in meters (m).

Field strengths from xed RF transmit�

ters, as determined by an electromag�

netic site survey

should be less than the compliance level

in each frequency range

. 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

aected by absorption and reection from structures, objects and people.

Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If

the measured 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.

Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
