Recommended Separation Distances Between Portable and Mobile RF Communication
Equipment and the TheraKair Visio MRS
The TheraKair Visio MRS is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the TheraKair Visio MRS can help prevent
electromagnetic interference by maintaining a minimum distance between the portable and mobile
RF communications equipment (transmitters) and the TheraKair Visio MRS 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 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.
