3-8 SurgiStat Low-Power Electrosurgical Generator Service Manual
EMC Compliance
EMC Compliance
Special precautions should be taken regarding the generator. Medical electrical equipment
needs special precautions regarding EMC and needs to be installed and put into service
according to the EMC information provided in this manual.
Understand that only the accessories supplied with, or ordered from Covidien should be
used with your device. The use of accessories, transducers, and cables other than those
specified, may result in increased emissions or decreased Immunity of the SurgiStat
generator. The generator and its accessories are not suitable for interconnection with
other equipment.
Portable and mobile RF communications equipment can affect medical electrical
equipment. The SurgiStat should not be used adjacent to or stacked with other equipment
and use adjacent to other devices or stacked with other equipment, the SurgiStat
generator should be observed to verify normal operation in the configuration in which it
will be used.
Recommended separation distances between portable and mobile RF communications
equipment and the SurgiStat Low-Power Electrosurgical Generator.
The SurgiStat is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the SurgiStat can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the SurgiStat 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.
