Guidance and Manufacturer's Declaration – Electromagnetic Immunity
Immunity Tests
Cryo Cuff IC is intended for use in the electromagnetic environment specified below. The customer
or the user of Cryo Cuff IC should assure that it is used in such an environment.
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 Cryo Cuff IC is used exceeds the applicable RF compliance
level above, Cryo Cuff IC 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 150 kHz to 80 MHz, field strengths should be less than [V

Electromagnetic Environment - Guidance
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/V ]√P 150 KHz to 80 MHz
1
d = [3.5/E ]√P 80 MHz to 800 MHz
1
d = [7/E ]√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
