Recommended separation distances between portable and mobile RF
communications equipment and the Fitvibexcel Pro Medical
The Fitvibexcel Pro Medical is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the
Fitvibexcel Pro Medical can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Fitvibexcel Pro Medical 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 applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
