GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
The Compex stimulator is intended for use in the electromagnetic environment specified below. The customer or the user of
the Compex stimulator should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the Compex stimulator, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2,5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance
in metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
surveya, should be less than the compliance
level in each frequency rangeb.
Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the Compex stimulator is used exceeds the applicable RF compliance level
above, the Compex stimulator should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Compex stimulator.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
