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