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.

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

ELECTROMAGNETIC ENVIRONMENT -
GUIDANCE
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 meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
