The Compex Fit is designed for use in an electromagnetic environment in
which radiated RF waves are controlled. The buyer or user of the Compex Fit
can contribute to preventing electromagnetic interference by maintaining
a minimum distance between RF portable and mobile communication
appliances (transmitters) and the et Compex Fit according to the table of
recommendations below and according to the maximum output power of
the telecommunication appliance.
In the case of transmitters whose maximum output power is not shown in the table above, the
recommended spacing of d metres (m) can be calculated using the appropriate equation for the
transmitter frequency, where P is the maximum output power of the transmitter in watts (W) as
set by the transmitter manufacturer.
NOTE 1: At 80 MHz and at 800 MHz, the spacing for high frequency amplitude is applied.
NOTE 2: These guidelines may not be appropriate for some situations. Electromagnetic wave
propagation is modified by absorption and reflection due to buildings, objects and
persons.
