ClosureRFG Radiofrequency Generator
Electromagnetic Interference (EMI)
Separation Distances
Recommended separation distances between portable and mobile RF communications
equipment and the ClosureRFG generator
The ClosureRFG generator is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the ClosureRFG generator
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the ClosureRFG generator
as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
Electromagnetic Interference (EMI)
The ClosureRFG radiofrequency generator has been tested for EMI emissions and
susceptibility to emissions from other equipment according to established standards and
limits.
Note:
For electromagnetic compliance information, see
Electromagnetic Compliance
(EMC)
on page 11-4.
The ClosureRFG generator might cause interference that can affect other
equipment.
Such interference would most likely occur during RF treatment mode, but
could occur at any time.
The ClosureRFG generator is susceptible to EMI from other equipment.
This could
result in inaccurate RF power delivery and possible injury to the patient. Additionally, RF
