311061526 Rev. CVULCAN™ Generator Operations/Service Manual
Guidance and Manufacturer’s Declaration (continued)
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity*
The Smith & Nephew VULCAN™ Generator is intended for use in the electromagnetic environment specified
below. The customer or user of the VULCAN Generator should assure that it is used in such an environment.
Immunity Test IEC 60601 Test Level Compliance Level
Electromagnetic
Environment – Guidance
Portable and mobile RF communications
equipment should be used no
closer to any part of the VULCAN
Generator, 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
3 Vrms
d = 1.2 √ P
Radiated RF
IEC 61000-4-3
3 V/M
80 MHz to 2.5 GHz
3 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 strength 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 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, land mobile radios,
amateur radios, AM and FM radio broadcasts, and TV broadcasts 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 VULCAN Generator is used exceeds the applicable RF
compliance level above, the VULCAN Generator should be observed to verify normal operation. If abnomal performance
is observed, additional measures may be necessary, such as reorienting or relocating the VULCAN Generator.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
*Applies only to Smith & Nephew VULCAN Generator REF 7210812. Does not apply to Smith & Nephew VULCAN Generator REF 7209673.
