Recommended separation distances between portable and mobile RF
communications equipment and the Cold Therapy Unit
Iceman is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of Iceman can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and
Iceman 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 MHz and 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.
