Table 4 - Recommended separation distance between portable and mobile RF communi-
cations equipment and the NuStep® T4r Recumbent Cross Trainer
The NuStep® Recumbent Cross Trainer is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the NuStep® T4r Recumbent Cross Trainer can
help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the NuStep® 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
metres (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 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 refl ection from structures, objects and people.
