mobile radios, amateur radios, AM and FM radio broadcast, and TVbroadcast 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 MedTrack treadmill is
used exceeds the applicable RF compliance level above, the MedTrack treadmill should be observed to verify
normaloperation. If abnormalperformance is observed, additionalmeasures may benecessary, suchas reorienting
or relocating the MedTracktreadmill.

Table X-4 Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the Medtrack Rehabilitation Treadmills
The Medtrack Rehabilitation Treadmills are intendedforuse in an electromagnetic environment in which radiated
RF disturbancesare controlled.The customerorthe userofthe Medtrack Rehabilitation Treadmills can help prevent
electromagnetic interference bymaintaininga minimum distance betweenportable and mobile RFcommunications
equipment (transmitters)and the Medtrack Rehabilitation Treadmills as recommended below, according to the
maximum output powerofthe communications equipment.
Rated Maximum Output
Power of Transmitter (W) Separation Distance According to Frequency of Transmitter (m)
150 KHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
d = 1.2 d = 1.2 d = 2.3
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
Fortransmitters rated at a maximum outputpowernot listedabove, the recommended separationdistance d in
meters (m) can be estimated usingthe equation applicable to the frequency of the transmitter, where Pis the
maximum output powerrating ofthetransmitterin watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz,the higherfrequency rangeapplies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorptionandreflection from structures, objects, and people.
NOTE 3: Tests were verifiedwithshielded input/output cables only.
