Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Medtrack Rehabilitation Treadmills are intended for use in the electromagnetic environment specified
below. The customer or the user of the Medtrack Rehabilitation Treadmills should assure that they are used in
such an environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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.
NOTE 3: Tests were verified with shielded input/output cables only.
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 broadcast cannot be predicted theoretically with accuracy. To assess the elec-
tromagnetic 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 normal operation. If abnormal performance is observed, additional measures may be nec-
essary, such as reorienting or relocating the MedTrack treadmill.
b.Over the frequency range 150 kHz to 80 MHz, field 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 MedTrack treadmill,
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
=
80 MHz to 800 MHz
d = 1.2 P
800 MHz to 2.5 GHz
d = 2.3 P
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 fixed RF transmitters,
as determined by an electromagnetic site
a
survey , should be less than the
compliance level in each frequency range
