Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the Medtrack Rehabilitation Treadmills
The Medtrack Rehabilitation Treadmills are intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the
user of the Medtrack Rehabilitation Treadmills can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Medtrack Rehabilitation Treadmills
as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
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.
