RECOMMENDED SPACING BETWEEN A PORTABLE AND MOBILE COMMUNICATION DEVICE
AND THE COMPEX STIMULATOR
The Compex Stimulator is designed for use in an electromagnetic environment in which radiated RF waves are controlled.
The buyer or user of the Compex Stimulator can contribute to preventing electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communication devices (transmitters) and the Compex Stimulator
according to the table of recommendations below and according to the maximum output power of the telecommunication
device.

FROM 150 KHZ

FROM 80 KHZ
TO 800 MHZ
D = 1.2 √P
FROM 800 MHZ
TO 2.5 GHZ
D = 2.3 √P

100 12 12 23
In the case of transmitters whose maximum output power is not shown in the table above, the recommended spacing of d in
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.
