Portable and mobile RF
communications equipment should
be used no closer to any part of the
Cold Therapy Unit, including cables,
than the recommended separation
distance calculated from the
equation applicable to the frequency
of the transmitter.
Recommended separation
distance:
d = [3.5/V1]√P  KHz to  MHz
d = [3.5/E1]√P  MHz to  MHz
d = [/E1]√P  MHz to . GHz
where P is the maximum output
power rating of the transmitter in
watts (W) according to the
transmitter manu-facturer and d is
the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
a
should
be less than the compliance level in
each frequency range.
b
Interference may occur in the
vicinity of equipment marked with
the following symbol:

NOTE 1: At  MHz and  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 Iceman is used exceeds
the applicable RF compliance level above, Iceman should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the Cold Therapy Unit.
b
Over the frequency range  kHz to  MHz, field strengths should be less than [V1] V/m.
