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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
a
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 Sport Elite are used exceeds the applicable RF
compliance level above, the Compex Sport Elite should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the Compex Sport Elite.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

SPECIFICATIONS
Electromagnetic Environment -
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:
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
a
compliance level in each frequency
