RECOMMENDATIONS AND DECLARATION BY THE MANUFACTURER
CONCERNING ELECTROMAGNETIC IMMUNITY
Compex Stimulator is designed for use in the electromagnetic environment stipulated below. The buyer or user of the
Compex Stimulator must ensure it is used in this recommended environment.

Portable and mobile RF communication devices must
only be used relative to the Compex Stimulator and its
wiring at a distance which is not less than the spacing
recommended and calculated using the appropriate
equation for the transmitter’s frequency.
Recommended spacing
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 of the transmitter
in watts (W) set by the manufacturer’s specifications and
where d is the recommended spacing in metres (m).
The field intensity of RF fixed transmitters, as determined
by an electromagnetic survey a must be less than the
observance level to be found in each frequency rangeb.
Interference may occur close to any appliance identified
by the following symbol:
NOTE 1 At 80 MHz and at 800 MHz ,the 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.
a The field intensity from fixed transmitters, such as radio telephone base stations (cellular/wireless) and a mobile radio, amateur
radios, AM and FM radio transmissions and TV transmissions cannot be predicted with any accuracy. It may therefore be necessary
to consider an analysis of the electromagnetic environment of the site to calculate the electromagnetic environment coming from
fixed RF transmitters. If the field intensity measured in the environment where the Compex Stimulator is located exceeds the
appropriate RF observance level above, the Compex Stimulator should be monitored to ensure it is operating properly. In the event
of abnormal operation, new measures may then be imposed, such as realignment or movement of the Compex Stimulator.
b Above the frequency amplitude from 150 kHz to 80 MHz, the field intensity must be < 3 V/m.
