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 Edge are used exceeds the applicable RF
compliance level above, the Compex Edge should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the Compex Edge.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Guidance
Portable and mobile RF communications
equipment should be used no closer
to any part of the Compex Sport Elite,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance:
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to
80 MHz
Not Applicable d = 1.2√P
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to
2.7 GHz
10 V/m
80 MHz to
2.7 GHz
3 V/m
10 V/m
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
