Electromagnetic Compatibility (EMC)
The T2100 Treadmill is intended for use in the electromagnetic environment on which
radiated RF disturbances are controlled. The customer or the user of the T2100
Treadmill can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters)
and the T2100 Treadmill as recommended below, according to the maximum output
power of the communications equipment.
Recommended Separation Distances
Rated maximum
output power of
transmitter in watts
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can estimated using the equitation 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 separation distance for 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.
