Recommended separation distances between portable and mobile RF communications equipment and the PREVENA
PLUS™ 125 Therapy Unit
The PREVENA PLUS™ 125 Therapy Unit is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the PREVENA PLUS™ 125 Therapy Unit can help
prevent electromagnetic interference by maintaining a minimum distance between the portable and mobile RF
communications equipment (transmitters) and the unit 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.
